Why is my local Mz3 Title no longer working in a Browser?

Since Flash Version 23 you no longer can show “Online” books, i.e. Mz3 Titles stored on your local disk, in a browser.
This is on purpose;  for sucurity matters!
See this answer from Adobe.


  • Upload your content to a “real” server with e.g. any FTP program and start the book over the internet
  • Use a local webserver;  installed on your local disk, e.g.  “XAMPP”
    you then can store your online package in e.g. a subfolder in C:\xampp\htdocs
    And open your book using this kind of address: /localhost/yourBookFolder/index.html  in your browser.
    You still might have to confirm with a right click with your mouse. But then everything, including video, will work
  • Use mz3Viewer
    This is the special “APP” made for local use.
    mz3Viewer actually is available for Windows, MAC/OSx and Android computer and can be downloaded for free from our download page.
    You can enjoy all Mz3 Titles with all features without problems; independent on a browser or an internet connection.
    In mz3Tool you’ll find a “SHOW” button once you installed mz3Viewer; as a “one-click” access to your local book. And the best: mz3Viewer opens the book you’re actually working on.
    Probably the fastest and most comfortable way. There’s not even a need to PUBLISH Online or Offline.
What’s the best license for me?

Depends… 😉

Please see the special blog post about this topic:
License Overview

What can I do with MegaZine3?

The number of resaons and motivation are as numerous as the number of features and the amount of flexibility of MegaZine3 😉

The possible solutions are unlimited and mostly depend on your own creativity, curiosity and interest to create something new.

There are a lot of excellent arguments (see the incomplete list below), but it also is a lot of fun building something on your own  and seeing dreams and imagination come true! And all without being an expert in computer science, design and graphics.

Examples of Private Use

Alternative PDF Reader

If you prefer flipping in books because it is the natural UI and find scrolling in long PDF files boring: Quickly convert any PDF file (must be unprotected!) into a book. With all the options for zooming, setting bookmarks, searching and browsing


Every Mz3 Title (your “book”, i.e. anything converted into an “mz3 file”) also can be presented as slideshow. Be it Online (via Internet, e.g. on your website) and Offline (as stand allone “App”, installed on a local PC or tablet)

Photo books

An ideal way to create special books with photos to share with friends (or “the world”). As classical photo collection or brushed up with videos and music. Or even links and animations!

Wedding Books

As an additional service from your photographer, or created by you out of your own photos or those from friends and guests.
Enriched with video snippets and perhaps even scanned documents (Birth Certificate, first driver license, first shared restaurant bill, … Probably not your marriage contract 😉

Favorite Books

Photos of your kids or pets. Or about your sports or genealogy or …


Collect anything you like: photos, scanned things, paintings, … whatever 😉

Travel Reports, Travel Album

Photos, reports, descriptions information, geo locations, travel itineraries, … All collected in a special travel book.


The affordakle PRIV license even can be used to test the market for own, self-published  “eBooks”. As long as those books are not (yet) sold and no ADs are placed, there is no need for a PUBL license.

School Books, Association Newspapers

Again: All options are available. And as long those publications are not sold (or ads are placed), those are covered by a PRIV license.

XML Format lernen

Für die Wissbegierigen bietet mz3Tool auch die Möglichkeit, sich praxisorientiert mit dem XML Format zu beschäftigen. Für die normale Nutzung wird dies nicht (mehr) benötigt. aber da alle Konfigurationsdateien im XML_Format gespeichert werden und mit jedem Editor angeschaut und verändert werden können, kann man gefahrlos eigene Versuche machen oder einfach analysieren, was mz3Tool “so macht”. Und auf diese Wiese lernen, was es mit <tags> und Attributen, Nodes, etc. so auf sich hat. Eine Suche nach “XML” bringt bereits viele Treffer denen man nachgehen kann…

Examples of Business Use


Business, finace, annual reports; as supplement to the (paper) PDF version; distributed over the Internet or on media.

Audio Books

Audio and reading books for children.

Children’s Books

Picture books, interactive books with quizzes, jigsaws, puzzles, games

School Books

For all ages and grades: As reading book, puzzle book, text book reference book… With video documents (embedded or via link) and interactive components.


A book is easily created out of a PDF file, and can be enriched with image galleries, video, audio and links. Bookmarks (fix or editable by the user) and search can be used or any other of the plenty features of MegaZine3.

As Online of/and Offline version. Distributed via your own server or via  App stores, as special app or just as “Mz3 Package” for use in the free mz3Viewer.


All kind of magazines can be presented as Mz3 Title. Those with nice and high quality graphics take biggest profit out of the numerous special features for improved user experience.


Optins like Zoom, automatic (liquid) scaling, search and vector fonts support the sometimes very small fonts and big pages of newspapers.


To showcase products, top quality brochures are created in a breeze. Often multi lingual support and animations are included.

Product Catalogues

This is the classic use case for page flip solutions. Everybody know the catalogues of hotels, travel agencies and sellers of goods of any kind.

Even local ad-papers can be published fast and easily for little money.

Multi-Lingual Books

With the perfect support of several languages “in parallel”, any multi-lingual book can be realized with MegaZine3.

Is this a free PDF converter?

Yes, but also much more!

The free mz3Demo version does the conversion of any non encrypted PDF file.

NO watermarks

NO time restrictions

NO registration needs

NO Cloud service (you run it on your Windows or OSx/MAC computer!).

For up to 10 pages with a single run and unlimited pages, if starting the conversion (n / 10) times 😉

You can choose what kind of conversion you need; and set the required qualitities.
The conversion method can be selected from a dropdown list in case of problems (e.g. transparency layers).

A PDF file with single or double pages can be converted automatically into these formats:

  • SWF Files (FLASH files)
  • PNG files
  • JPG files
  • Thumbnails (special JPG files, scaled and split if needed)

Resolution, quality and size can be adjusted within wide ranges.

If you want to convert hundreds of pages with all the image formats available in a single run (start it and drink a coffe), you can get the

PRIV version for a bargainactually for less than $20 (without applicable VAT).

And you’ll get all the advantages of MegaZine3 on top:

  • Convert your PDFs into nice and comfortable to work with digital, flippable books; automatically on your Windows or OSx/MAC computer!
  • Use the results with any Browser over the Internet (with FLASH or without Flash as pure Javascript version).
  • Enjoy it from a local disk or local media (memory stick, DVD) with the free mz3Viewer.
  • Share it with friends: A ZIP file containing everything needed is created with a single click

All that is also possible with the DEMO version. But with watermarks on left pages of the Mz3 Titles…


Are Video Tutorials available?

Yes, actually available on Vimeo: Vimeo Channel

The videos we uploaded to YouTube Playlist are outdated and had been taken Offline.

What kind of documentation is available?

Depending on your level of expertise, the kind of question you have and what it is about, you should try what option is the best fit for you:

  • Video Tutorials
    We started to create a new series of video tutorials.
    All will be available on Vimeo in this Video Tutorial Collection
  • FAQs
    You already found this source of information 😉
  • New Forum: Questions and Answers
    You also can search in our “Questions” area, where everybody can ask questions and provide answers; similar to stackoverflow, our preferred source of information 😉
    We actively monitor all questions and provide answers if possible and appropriate. This is your access to free support; if you own a license or not.
  • MegaZine3 Blog
    We started a blog, which in future should become a collection of all kind of information
  • WIKI
    All details about the core program, MegaZine3, can be found in our WIKI
  • API
    For programmers only: definition of the API (programming interface) of MegaZine3. This data is only needed for the case that own plugins will be developed.
  • Twitter
    Not really a source of “documents”, but a way to hear about changes like new a version earliest.
  • Facebook
    Like Twitter: not meant as source for details. We still have to find out how we best can make use of it.
  • old MegaZine3 Forum (outdated!)
    Just for the sake of completeness: At the early beginnings, when MegaZine3 was developed as OpenSource program, this forum was a great way to communicate with early adopters.
    After the core was developed, activities went down and actually the topics in the forum are completely outdated. But who is interested in the history… feel free to have a look. It still is working.

And if all that does not help, please contact us. But : only after you tried all other options, especially the  New Forum: Questions and Answers area. And only if you think your question is too special or touches privacy. Customers owning a license have best chances for a reply.
For individiual support we offer our MZ3-OPT-SVC option. There you can buy some of our time.

How do I create a flip book? Any skills needed?

The conversion is a multi-step process, but most is done automatically. So relax, it is easy 😉

  • First the PDF information (page size, page count, …) will be read and shown. This is done with pdfinfo (an open source program)
  • Once the conversion started (after clicking the convert Button), several steps are performed in sequence:
    • Text is extracted with pdftotext. This file is needed for the search plugin.
    • The PDF conversion is perfomed by the OpenSource Tool pdf2swf.  mz3Tool dynamically, based on the parameters set in mz3Tool, creates and starts a script for that.
      For Windows a bat file is used, and for OSx a Bash script.
    • After that swfrender is called to convert SWF files into PNG files; if needed.
    • And finally, if requested and if ImageMagick is installed, all JPG files are created.

    Error and info messages created by mz3Tool and the open source tools are collected and saved as log file(s); available for review with the “LOGs” button in mz3Tool.

Using PDF files as base for any kind of publications is a common approach, and makes the creation of Mz3 Titles (all kind of digitally presented flippable documents) very easy.

Since all information needed, like page size and page count, is read from the PDF document, a creation can run fully automatic.

These are the steps:

  • First a PDF file must be selected by the user; either in opening that PDF file ina a file explorer,  or dragging the file into the IN field. Once PDF files have been selected, they are saved in a list and easily can be picked the nect time. The last opened file is used at start.
  • Once a valid PDF file was selected, the page and document information (page size, page count, encryption status, creation/modification date) is read from the PDF file, is is shown in the right top panel and can be adjusted.
  • After all preparations like setting the page range, adjusting the page size, defining the kind of the cover pages (flexible like paper or hard cover) have been made. the conversion can be started in clicking CONVERT.

That’s all a standard user will and has to do! Everything else is done by mz3Tool, based on the parameter settings. At the end of the conversion the final Mz3 Title (your digital, flippable document) is built and presented in the preview area. You can watch the process and wait for the result 😉

If everything is OK, the result can be “published”, i.e. the “Online” and “Offline” packages can be created with a click on PUBLISH. The Online package consists of all files and folders that can be uploaded to a server to present the document over the Internet. WHereas the Offline package is a single ZIP file (with the special ending “mz3z”), that can be distributed via email, any Cloud service like Dropbox, memory stick, DVD and more.

(Only) if you are curious and interested in the “behind the scenes” stuff, read on! It will become a bit technical, though.

  • First thing done when the Conversion process is started (with a click of CONVERT) is to build a file with all textual information, extracted form the PDF file with the help of the Open Source tool “pdftotext“. That data is used by the SEARCH function.
  • To convert single PDF pages another OpenS Source tool is used: “pdf2swf“.
    mz3Tool controls such tools via dynamically created script files. On Windows we  create a “.bat-File”, under OSx it’s a Bash-Skript.
  • The script fle is started and does it’s job in the background; mz3Tool monitors status messages and continues with the next stpes once the conversion is done.
  • Then another too, “swfrender”, is started and converts all SWF files into PNG bitmap data.
  • Only in case the optional tool ImageMagick is installed (that has to be done independently on the installation of mz3Tool or mz3Viewer; see answers on respective questions below)  and if JPG files are needed (e.g. to generate thumbnails or files for the Javascript alternative), the PNG data is converted into JPG files; depending on the needs and parameter settings with scaling and splitting (for spread and double pages).
  • Once all image data is created, the control file for MegaZine3, the so called “mz3 file” is built. Again considering all default or adjusted parameters.
  • At the end of this job all files are available and the final Mz3 Title is presented in the preview area..
  • With SHOW the Viewer wills tart (if mz3Viewer was installed, of course) and the flippable document can be viewed in full scale.

Closing the preview area shows two buttons that help tracking problems: “Logs” to show the list of warning and error messages (the depth of details can be adjusted) and “Status” with Subview “Statistics” to show details about what steps have teraminted with success, what and how many files have been converted/created, …

How to start?

Please follow these steps:

  • Check the Video Tutorials
  • Download the mz3Tool installer from our website (called mz3Demo as the free version)
  • Start the  mz3Tool.msi (Windows) or mz3Tool.apk (OSx) installer program and accept/follow the suggested settings
  • Double click the mz3Tool icon, which can be found on your desktop (if needed: start explorer/finder, open the program (86) / applications folder and search for mz3Tool).
  • Search for a PDF file – either in using the “browse” button, or in using explorer/finder to find a PDF file, that then can be dragged & dropped into the input line
  • Click the CONVERT button, accept to convert just 10 pages to get started, and… wait 😉
  • Once all (10) pages are converted, the Mz3 Title is created automatically and will show up in the preview area
  • To see the prepared “book” in mz3Viewer click on “SHOW” (mz3Viewer must have been downloaded and installed first)
What are: Mz3 Titles, mz3 files, mz3Tool, mz3Viewer and MegaZine3??

Mz3 Title

An Mz3 Title is the common name for all kind of “documents” you converted into a digital document.

Like: books, newspapers, magazines, reports, brochures, ads, photo books, flyer, manuals, websites, …

An Mz3 Title usually represents a complete “package” (e.g. an “Online” or “Offline” package), which contains not only the MegaZine3 software and the mz3 configuration file, but also all assets, i.e. images, video and audio files, plugins, configuration files, …

mz3 File

An “mz3 file” is the main configuration file describing almost everything about the Mz3 Title.

An mz3 file is the final “output” of mz3Tool and used by the core software MegaZine3 to show the Mz3 Title.

It is an XML file, structured like a real book:

  • After the general description of the “book” in a tag, there are
  • chapters, bracketed with tags, which contain
  • pages, defines with a pair of tags, which contain
  • an image representing the page content and defined with a pair of <img></img>, and probably several other “elements” like
  • video files (<vid></vid>)
  • audio files (<snd></snd>)
  • clickable areas/links (areas/links:  <area></area>)
  • and many more

The mz3 file is named after it’s standard extension: .mz3; which will/can be registered with mz3Viewer. Then a double click on a mz3 file will start the viewer and show the Mz3 Title.


mz3Tool is the general tool with comfortable GUI to create Mz3 Titles. It is your “development and design tool.

With mz3Demo a free demo version is available for download, whcih offers full functionaltiy. A license key acannot be entered and on pages a wateramrk is printed, though.

mz3Tool supports converting PDF files into flippable books, creating”empty books”, adding “elements” like photos/images, video and sound, configuring the look&feel and making the book interactive; in adding links and clickable areas.

Look&Feel: select colors, define what functions to use (e.g. zoom or search), use own icons for the buttons, disable/enable effects

Elements: all stuff added to pages, like video, images and audio. And clickable areas to jump to a page or open an external link.


mz3Viewer if a free tool to show Mz3Titles  on a Windows- or OSx/MAC Computer: or on an Android Tablet.

With mz3Viewer no Internet connection and now browser and no FLASH support is needed. Data located on a local disk or an attached device like a memory stick or DVD player, is used. mz3Viewer can handle mz3- and mz3z-files (zipped MZ3 Offline-Package)..


MegaZine3 is the free core Software of the framework for “digital publishing” and interprets the main configuration file with the extension “.mz3” (which also is called the “mz3 file”). Based on those parameters the publications are presented the way the designer intended. MegaZine3 is modular, fast and open , i.e. expandable via plugins, and can be controlled by other programs via the detailed “API” (program interface).

MegaZine3 is hidden by mz3tool. All configuration id done by mz3Tool.

MegaZine3 is embedded in mz3Tool and mz3Viewer, and also provided as FLASH and Javascript program to be updloaded to your server.

What is ImageMagick? And where do I find it?

ImageMagick is a very powerful OpenSource tool for all kind of image manipulation.

It is used by mz3Tool to create JPG files out of PNG files for the use in the MegaZine3 Javascript Version  and also for the thumbnails, if those should be preloaded (enabled by default).

ImageMagick is also used to split the thumbnails for spread pages into two single pages and to scale them down to 25% of the page size (as requested by MegaZine3).

ImageMagick can be downloaded from the download page of ImageMagick for Windows or as package for OS/x.

How to do so will be shown in a special video on this topic soon!


Based on a recent (20160505) security alert it is recommended to add these lines to the policy.xml file:

<policy domain=”coder” rights=”none” pattern=”EPHEMERAL” />
<policy domain=”coder” rights=”none” pattern=”URL” />
<policy domain=”coder” rights=”none” pattern=”HTTPS” />
<policy domain=”coder” rights=”none” pattern=”MVG” />
<policy domain=”coder” rights=”none” pattern=”MSL” />

These lines have to be included below the <policymap> tag.
The file most probably is located (at least on Windows) in the root directory .

For details on policy.map and optional locations of the file on Linux and Windows please visit ImageMagick’s homepage

What programs do I need to create “books”?

mz3Tool or mz3Demo

mz3Tool is the core tool to convert PDF files and to create flippable books (we call all digital documents shown with MegaZine3 “Mz3 Titles”).
It also contains all software variants of MegaZine3.

mz3Tool is available for Windows and OSx/MAC, either as free Demo Version mz3Demo or as full version mz3Tool for customers with a license .

MegaZine3, the core software interpreting mz3 files and showing the fkippable books, is part of mz3Tool.


mz3Viewer is a stand-alone viewer for Mz3 Titles, available for Windows, OSX or Android. It is completely free and and available for download on our megazine3.de homepage (click the DOWNLOAD button). mz3Viewer can find most MZ3 titles located on the main disk drive automatically.
Drag&Drop and Copy&Paste is supported (needed for Mz3 Titles that are not found automatically, like Mz3 Titles on external drives or a server).

mz3Viewer allows to view Mz3 Titles which are located on the local PC (disk, memory stick, DVD, …) or on a server (accessible over a local network or the Internet).

Optional: ImageMagick

ImageMagick is a great OpenSource program used to create JPG files.
ImageMagick (the convert tool) is needed for the Javascript fallback (if PNG files are too big or not an option) and the “preload thumbnails”.
Thumbnails can be created “on-the-fly” by MegaZine3, but until those are built, empty pages are shown. Preload-thumbnails can be loaded at the start of MegaZine3 and are available almost immediately.

For mz3Tool either the Windows or OSX / MAC version of ImageMagick is needed.
There will be a video tutorial available soon, showing how to install ImageMagick for Windows or OSx.

 Optional: Adobe Air Framework

On request the viewer is available as AIR installer also. Only in that case the Adobe AIR Framework is and must be installed upfront.
Adobe AIR can be downloaded from the Adobe download page.

Why does the conversion take so long?

The time needed to convert PDF pages depends on many factors:

  • The size of the PDF file
    Every page is converted with a separate call of the tool we use for the conversion (pdf2swf). And every time the complete file must be read before the respective page can be extracted and converted.
    Therefore big files take much longer than small ones! Therefore we suggest to finish all basic work (selection of the plugins, adjustments of the gui and parameter settings like stiff and fold effects) before creating the final Mz3 Title with all pages.
  • The size of the created images
    If JPG files are created, the bigger the size the longer the creation time.
  • The number of images that have to be built
    If you want/need several quality levels (up to three are supported with mz3Tool), the time will be 2 to 3 times longer than for a single quality version (for obvious reasons ;-))
    But not only the number of quality levels increase the number of images and time needed for the conversion. Read on!
  • The kind of images requested
    If JPG files have to be created, actually a 3-step process is needed: first a SWF file per page will be created out of the PDF pages.
    Then that SWF file is converted (rendered) into a PNG file.
    And finally that PNG file is converted into a JPG file.
    Although the PNG and JPG creation is much faster than the first step, the SWF creation, it also adds to the total time.
  • The options you enabled
    If thumbnails for a pre-load are requested, those have to be built like the JPG images for the Javascript version:
    First a SWF file is generated, then a PNG file, and finally the one (in case of single pages) or two (in case of spread pages) JPG files with the correct size.

The fastest way is: only SWF files, no thumb nails, no Javascript version: A sibngle PDF to SWF conversion per page.
The most extreme setup is: all three qualities as JPG files plus the Javascript option plus thumbnails.

This would request (3 qualities + JS + thumb for swf = 5 (!) ) + 5 (for PNG) +  5 ( for JPG) =  15 conversions per page!
So again: Better test with a few pages first. And do the final run with hundreds of pages and a dozen of image formats after everything is tested.  And then enjoy and take a coffee break (or go out for lunch or to bed, depending on your settings ;-)!
