ePub MD Viewer

ePub MD Viewer is an application for quickly open and read book files in ePub format. It can also quickly open MD (Markdown) files with the same render quality as in GitHub.

This is the epub-md-viewer.com (and former epubviewer.xyz and mdviewer.com) landing page

The need for this application arise from the fact that other applications are either too slow, do not have a good render quality or are extracting the book on disk and do not delete it after (such as the defunct Edge). Also, for other similar applications it is not easy to change the font and the font size for the whole book, there are always some parts which remain different than the others. So, the idea was to have an application that can be used to quickly open (then preview and close) a book by double clicking on it in a folder with a lot of books. However, if a book will be selected by the user to store its customizations, the bookmarks and the display settings will be saved on disk (in the operating system provided location).

Features

Quickly open and read ePub books
Nothing is written on disk by default, the ePub file is opened and processed entirely in memory!
Customizable font and style can be forced for all elements (not only paragraphs and headers)
For security, no external links are followed by the application, the embedded ones are ignored, and the ones in page are not opened even if the user clicks on them
If the user selects the option to save information on disk, then and only then the customizations done for a book (including bookmarks) will be stored
The application can also open MD (Markdown) files, and render them either identical to GitHub, or in a more "Google" style

Notes

For ePubs no Internet links are opened, but for MD the links are opened, the ones inside the MD will be downloaded and the ones clicked by the user will be opened in an external browser
No MathML is rendered if the book contains mathematical expressions; it was implemented, it worked OK but the size of the library was too big to be included only for this functionality
No versions were done/tested for 32 bits platforms, only 64 bits platforms are available

Download

ePub MD Viewer is written entirely in Electron, and so it can work on different platforms, download the version corresponding to the user platform. Currently, only the Windows application is available:

Windows 64 bits: download new version 2.0.1
