EPub to APP, convert EPUB ebooks into secure apps

Convert ebooks from EPUB format to secure ebooks for Windows with HTML Executable and EPub to APP. The “EPub to APP” add-on lets you choose an ebook in EPUB format and generates an entire HTML Executable project for you in some clicks. Then compile your EPUB source files into stand-alone Windows applications or apps that can also be secured and customized with all of the features provided by HTML Executable.

Page navigation and formats of the initial EPUB are preserved.

Some possibilities:

  • Protect your EPUB source files against decompilation and copying once they are compiled in an application file.

  • Make user-attractive and customized ebooks thanks to the features of HTML Executable: skin, menus, toolbars, windows… may be changed the way you like.

  • Turn your EPUB ebooks into trial ebooks so you can sell them.

  • Disable print, select, copy, print screen key commands.

  • Add your own menus and toolbar buttons to your ebook navigator.

  • Distribute your EPUB ebook files safely: digital signatures with Authenticode (certificates) are supported.

EPub to APP is a free add-on for HTML Executable.

How to download EPub to APP and install it

You can download EPub to APP from its website and install it yourself. Or use the Web Update utility shipped with HTML Executable to install the add-on.

Requirements: EPub to APP requires HTML Executable in order to compile .exe files! EPub to APP is a free add-on for registered users of HTML Executable. Note that a Personal edition of HTML Executable is already enough to benefit from all features of EPub to APP.

How to use

  • Click “1) Open epub” and choose the .EPUB file you want to import. EPub to APP reads properties of the selected .EPUB file and displays the title and the author of the ebook.

  • Choose the HTML Executable project file that you want to create (.HEPX file) and the source folder: this is the folder where the content from the .EPUB file will be unpacked to.

Use the Browse button to select another location and EPub to APP will prompt you whether you want to automatically update other fields.

  • Click “2) Convert“: EPub to APP creates HTML pages extracted from the EPUB ebook file, and it generates the associated HTML Executable project.

  • Click “3) Open Project“: HTML Executable is launched in order to open the project. You can compile your ebook and run it:

On the screenshot above, the “Mobi Dick” ebook in EPUB format was converted into a stand-alone ebook.

Template HEPX File: you can use an existing HTML Executable project file as a template for your converted EPUB file. This template file (HEPX extension) must have been created with HTML Executable 4.5 at least. Existing settings such as toolbar options, splash screen, security profiles… will be kept. Basic settings (like window title) and source files will be replaced.


  • If you do not know HTML, ePUB ebooks can be written with editors like Sigil and easily transformed into secure ebooks with HTML Executable.

  • Only DRM-free EPUB ebooks (according to the IDPF specification) can be converted by EPub to APP.

  • EPUB 2.0 and 3.0 are accepted by the converter.

  • Navigation order (of EPUB ebooks) is preserved and converted in a Browse Sequence.
