What File Formats are Supported

eBooks Reader Pro supports the EPUB and MOBI formats. It may also open eBook files stored in the AZW or AZW3 format, depending on how they were created and/or encrypted*.

EPUB: short for electronic publication, EPUB is a popular format for publishers and consumers. Although it is a standard digital publication format for many digital books and publications, EPUB is not supported by Amazon Kindle reader.

MOBI: an eBook file format originated from Mobipocket, a French company acquired by Amazon in 2005, MOBI contains both book contents and DRM copyright protection to deter unauthorized access.

AZW*: based on the MOBI format, AZW is a proprietary format developed by Amazon for its Kindle readers in their earlier generations. It contains formatted book content and chapter marks.

AZW3*: as Amazon’s successor to AZW, AZW3 is created with the latest KF8 (Kindle Format 8) specification. It supports newer formatting capabilities based on HTML5 and CSS.

*Note: the app doesn’t officially support for AZW or AZW3 because files using these formats may be DRM protected and thus encrypted.

How to Access Display Settings

One of the best features of the app is the option of changing fonts and layout to suit your reading preference. You can access this option from the Display Settings menu. 

How to access the Display Settings menu:

  • Open an eBook file, preferably an ePub file, as not every eBook file format supports reformatting.
  • Locate the eBook Viewer Menu icon that looks like a hamburger icon (with three horizontal strips) in the eBook viewer window. There are two hamburger icons right next to each other. One is at the top of the side navigation menu bar, the other is to the right of it. Click the second hamburger icon.
  • This launches the Option flyout Window which contains the Settings menu.
  • Click the Display Settings menu icon , which looks like a cog.
