The Open eBook file format is used by an EPUB file, which stands for electronic publication. On your computer, tablet, e-reader, smartphone, or another device, you can download EPUB files and read them. More hardware eBook readers are supported by this open-source eBook standard than any other file type.

The most recent EPUB version is 3.2. It features built-in support for embedded interaction, audio, and video, and it works with the most recent versions of HTML, CSS, and SVG.

Opening an EPUB File

Most eBook readers, including the B&N Nook, Kobo eReader, and Apple’s Books app, support opening EPUB files. You can either use the Send to Kindle app to email the book to your reader, who will perform the conversion for you, or you can convert books using an EPUB converter to make them useable on the Amazon Kindle.

A number of free apps, including Calibre, Adobe Digital Editions, Apple Books, EPUB File Reader, Stanza Desktop, Okular, and Sumatra PDF, can be used to open these books on a computer as well.

A handful of the previously mentioned apps, as well as Readium, are available to Mac users for reading EPUB files.

Many iPhone and Android applications can read EPUB files. For Firefox and Chrome, there are additional add-ons and extensions that enable reading in the browser on par with other texts. Just two examples are Simple EPUB Reader for Chrome and EPUBReader for Firefox.

You may also view EPUB files on Google Play Books by adding them to your Google account and using the web client.

Since the structure of EPUB files is similar to that of ZIP files, you can rename an EPUB eBook by substituting the. epub suffix with.zip, and then open the file using your preferred file compression software, such as the free 7-Zip tool. You should discover the HTML version of the EPUB eBook’s contents as well as the styles and graphics that were used to construct the book inside. The format allows for the embedding of GIF, PNG, JPG, and SVG image files.

How to Change an EPUB Document

There are numerous methods:

  • The best program for this is Calibre. Most other eBook formats, including those supported by the Amazon Kindle, are converted as well. The following conversions are among those that are supported: EPUB, FB2, HTML, LIT, LRF, MOBI, PDF, PDB, RTF, TXT, and SNB.
  • An online EPUB converter worth mentioning is Zamzar. The website allows you to convert the book to formats like PDF, TXT, FB2, and others that are similar.
  • Making an EPUB file from a different document file, such as an AZW or PDF, can be done using the Online eBook Converter.

Although this method is probably less efficient than using Calibre or other online file converters, you can attempt converting the book by opening it in one of the other readers and selecting to save or export the open file as a different file format.

Can’t open it yet?

Misreading the file extension is one of the most frequent errors made when opening a strange file type. Even while different file formats have unique file extensions, it might be challenging to open or convert one because some of them remarkably resemble one another.

For instance, a PUB file is just one letter short of having the exact same suffix as an EPUB file, yet Microsoft Publisher uses PUB files as papers rather than eBook files.

Additionally, it is simple to mistake an EPM or EBM file for an EPUB file. Alternatively, EBM files are EXTRA! Both Basic Macro files and Embla Recording files are not eBook formats. The first is employed by Micro Focus software, whereas Embla RemLogic software is used in the second.

If you find that your file truly has a different file extension than what EPUB requires, read it again to determine what it is, and then look it up on Google or right here on Lifewire to find out more about what it is used for and how to open and/or convert it.
