mz3Viewer is available for WIndows 10 and MAC OSx. mz3Viewer “digests” mz3z- ot the original mz3-files and presents based on that information and data the respective Mz3 Book.
mz3Viewer offers the full functionality as you might know from the old Flash version; and more! No Browser is needed!
Here some key features:


SWF-Files support text in vector format, which makes them an ideal choice for all text-heavy papers!.
SWF file sizes usually are smaller than converted “Page Images” in JPG or PNG format.
Even the smallest Text can be scaled to any size without loss of quality; no pixels become visible.
Another advantage: The search feature can be used and any key found will be marked on pages.
That’s impossible with pure JPG or PNG files!


All available Plugins are supported:

  • Slideshow
    The Slideshow is a key plugin: Flip the book automatically time-based or controlled with the mouse. A perfect alternative for any Powerpoint Presentation ;-).
    Parameters like automatic start, time-before-flip, automatic loop and more are available as Book Parameters.
    A play/pause button is added to the navigation bar to control the book interactively with the mouse.
  • Search
    If in mz3Tool the search checkbox in the PDF-Convert-Window” is marked, additionally to the Page Images a text file, the search index file, is generated and the “search” Plugin is added to the plugin list.
    In case of SWF-files, the search feature is available and highlights text found on pages in the book.

Something impossible for pages based on image files (JPG, PNG) used as page background (page images).
We might consider some kind of search functionality again for the JavaScript version once v2.5.x becomes available..
Outlook: Once we add an “HTML Element” in future, a kind of highlight feature could become available…

In above example, you see on the left the list of pages with an excerpt and on the top right corner the search input field.
In the right image, all found text phrases are highlighted, and the “spy-glass-area” in the left top corner of this image indicates a high zoom factor.
In “touching” and moving the small blue area, the field of view of the page can be moved.
This also demonstrates the perfect text quality of SWF files!

Videos embedded in pages

Videos of any size can be arranged on pages. Even several videos may be placed on a page. But to not kill performance this is not recommended.
Double pages are supported as well; a video might spread across the folder in the middle of the book.
This functionality is planned for version 2.5.x of the Javascript version also. Actually, a video will open in a separate tab in the browser.


mz3Viewer shows one or more rows of “Bubbles”, which represent the pages. Hovering over a bubble will show the thumbnail of the respective page.
The JavaScript version shows a row of thumbnails instead.

Offline use

All data is located on the local computer; nothing has to be downloaded and no Internet connection is needed.
Pages will load much faster compared than in a browser with access to a server over the internet only.
If mz3Viewer is installed on a laptop and some Mz3 Projects are loaded/copied, those books can be viewed “on the road”, even if no internet access is available.

mz3z Support

All data needed by mz3Viewer is packaged in a ZIP compressed file with the extension .mz3z. This makes it easy publishing an Mz3 Book: One file only has to be shared; e.g. using any Cloud service like Dropbox.
Although the extension is named “.mz3z”, it is a pure Zip file. After renaming the extension to .zip the file can be opened with programs like 7Zip or WinZip; or even Windows and Mac OSx.
The reasoning behind the “mz3z” extension name: It is easy finding and identifying mz3Viewer files, those mz3z file types are assigned to mz3Viewer and mz3Viewer will start with a double-click on such file.
And the mz3Tool – mz3Viewer integration is easier.
mz3Viewer extracts and saves the data automatically.

Book Management

mz3Viewer remembers opened Mz3 Books and collects those Mz3Titles in a table.
To see that table of collected “books”, the book-view, i.e. the first Window that opens with mz3Viewer, must be closed.

Navigation Area

Above the table a navigation area listing the titles of the selected Mz3 Title (in the middle), the previous Mz3 Title (left) and the next Mz3 Title (right).
Those can be opened in clicking the buttons.
A click on the icon closes the header area and a click on expands it again.

Title Row with Icons
The icons in this row support the following features:

  • Open an Explorer/Finder window
  • Switch to the book view
  • Show a help window
  • Select the language of the help
  • Restrict the shown rows of the table ((filter function)

Table of Mz3 Titles

This table shows:

  • Modification Date
  • the name of the collected Mz3 Title
  • Path to the folder where the data of the Mz3 Title is located

Each column can be sorted with a click in the header cell of the column. The next click changes the sort direction.
With a double-click in a row, the respective book will open.
You also can select a row/book first and then open the book with a click on the button.

Filter Function

In the top right of the icon row, a search/filter input field is available. This helps to quickly restrict the amount of shown Mz3 Titles in the table. Especially helpful if the list becomes long over time.
This “intelligent” filter searches for names of Mz3 Titles with the provided characters “in a sequence”. It is not a usual search for “words”.

  • A book is listed if the Mz3 Title name contains the entered characters in the same sequence. Gaps (other characters in between) are allowed.
  • The closer the characters are, the more to the top of the list that book is placed.

The following examples will give you a better idea of this concept::

All 7 Files found
4 out of 7 files found

3 out of 7 files found
2 out of 7 files found
1 out of 7 files found

Pop-Up Menu

A right-click in a row opens a pop-up menu with some commands:

  • Remove Rows
    Take out a row (i.e. a book) from the table. That book no longer is selectable and shown.
    After a restart of mz3Viewer that book is available again (it was not deleted).
  • Delete Mz3 Project Folder
    Deletes the complete package: All data and configuration files. This cannot be undone!
  • Copy Path to Clipboard
    If you prefer working with the standard Explorer/Finder to browse/delete/move/copy files, the path to the root folder of the project can be copied with this command

Open the Book View

A double click on a row of the table or a click of the “Mz3” Icon activates the book view.
The header area can be hidden via the icon, and shown again via the icon.
Depending on the situation/use case the header options can be shown or hidden quickly.

mz3Tool Integration

In mz3Tool it is possible to Open the actual Mz3 Project in mz3Viewer.
All features and functions are available and not blocked like some operations in mz3Tool:

  • Links
  • Overlays
    Hovering over areas (clickable regions) will highlight that area as configured: with a border and a background color with defined transparency.
  • *Start Video’
    Video can be started and stopped
  • Page Flip via ‘page operation’
    mz3Tool blocks a click on the book edges or a drag of the page. In mz3Viewer all that is supported.
