    • Open your email application (e.g., Gmail) and compose a new message. Enter your own email address into the “To” field.
    • Click the paperclip or “Attach” button and select the EPUB file. When you return to the new message, click “Send.”

    • To see a list of your uploaded EPUB books next time you open Play Books, tap “My Library” and select “Uploads.”

Using iBooks for iOS and Mac

    • If the EPUB file is already on your iPhone or iPad, you can open it in iBooks

  5. Open your EPUB book in iBooks for Mac. If you want to read your e-book on your Mac, double-click the title in iTunes. The book will then appear in iBooks.

Using Calibre on a Computer

Transferring an EPUB file to a Kindle

  1. Convert the EPUB to a MOBI file. Before an EPUB file can be read on a Kindle Fire or Paperwhite, you’ll need to convert the file to the MOBI format in a converter like Calibre. See Using Calibre on a Computer to learn how to install and add books to Calibre.
    • Other converters are available, and most work similarly to Calibre. Use caution if you decide to install an EPUB converter with which you are unfamiliar, as other free software downloads may contain adware.
  2. Select a book to convert to the Kindle format. Click to select the book(s) you want to convert.
  3. Click the “Convert Books” icon. An output screen will appear.
  4. Select “MOBI” from the “Output Format” menu.

  6. Connect your Kindle to the computer via USB. Now you’ll prepare to copy the MOBI file to your Kindle.[8]
  7. Select the file in Calibre and click “Connect/Share”. A submenu will appear with several sharing options.
  8. Click “Connect to Folder.” A file browser will appear.
  9. Select the “Books” (Kindle Fire) or “Documents” (Paperwhite) folder on your Kindle. This is the folder where your Kindle books must be stored to be readable on your device.
  10. Click “OK.” The book will copy to your Kindle. It may take several moments to appear in your list of copied books on your Kindle.[9]

Using a Web Browser Add-On

  1. Visit your browser’s Add-On or Plugin Store. You can read EPUB files right in your web browser if you have the right browser plugin.
    • Chrome: Open Google Chrome and navigate to the Chrome Webstore.[10]
    • Firefox: Click the ≡ menu and select “Add-ons,” then select “Get Add-ons” in the left menu.[11]
  2. Search for “epub reader” in the search box. You will find several options to choose from, and most should be free. Be aware that most free browser add-ons and extensions are supported by advertisements.
    • A popular and reputable option for Firefox is “EPUBReader.”[12]
    • “Magicscroll” for Google Chrome is widely recommended and reputable.[12]
  3. Install the add-on or extension. Once you find a browser extension you want to install, click “Add to Firefox” or “Add to Chrome” to install it. After the installation, restart your web browser, if prompted.
  4. Click a link to an EPUB file to read it in your browser. Once the browser add-on is installed, clicking on an EPUB file on the web will immediately open the file as an e-book.

Converting an EPUB to PDF

  1. Save your EPUB file to a familiar folder. You can convert your EPUB file to several different file types, including PDF (which can be Open PDF Files). If you want the EPUB file to be readable on any device without having to install extra software (in most cases), convert it to a PDF.
    • If you have several EPUB files, you may want to move them all to the same folder to make it simple to convert multiple files.
    • See Reading an EPUB on a Kindle to learn how to convert an EPUB to the Kindle MOBI format with Calibre.
  2. Visit a free EPUB converter website. If you only need to convert one file, you can use a reputable EPUB conversion site like EPUB Converter. You can access a conversion site on both mobile and desktop devices.
  3. Click “EPUB to PDF Converter” in EPUB Converter. If you’re using Calibre, use Using Calibre on a Computer for the steps to add your EPUB to Calibre.
  4. Convert the file. The steps vary across converters:
    • EPUB Reader: Click “Add File” and select your EPUB file. Click “Start Upload.” The file will be converted automatically once the upload is complete.
    • Calibre: Click “Convert Books,” select “PDF” from the “Output Format” drop-down, then click “OK.”
  5. Click the download link on EPUB Reader. Skip this step if you’re using Calibre. The download link for your PDF file is listed beneath “Download Link,” right next to the name of the EPUB file.[13]
  6. Save the PDF to your desired location. If you download a PDF from EPUB Reader, save it to a location that you’ll remember so you can access it in your favorite PDF reader.
    • In Calibre, click the “PDF” link on the right panel next to “Formats” to open the PDF file in your default PDF reader.

Tips

  • Most readers do not support files protected by Digital Rights Management (DRM), such as books purchased from the Nook or Kindle store. To read DRM-protected EPUBs, you’ll have to remove DRM. While possible, this is not legal in most countries.
  • You can find free (non-DRM) EPUB books on sites like projectgutenberg.org and epubbooks.com.
