We’ll see what are the main formats compatible with Kindle to read e-books and how to convert unsupported others into one of them using a simple application.

Kindle compatible formats for reading e-books

Here is a list of all the formats compatible with Kindle to read e-books without problem.

  • AZW3: the format created by Amazon itself especially for the latest generation Kindle.
  • AZW: it is also possible to find ebooks in this format, also created by Amazon but in previous versions.
  • KPF– Using KPF files allows your e-book to be easily formatted and adapted to all Kindle devices. It is a reference method to avoid formatting problems.
  • MOBIAlthough it is currently also owned by Amazon, it was an open format that is compatible with Kindle as long as it does not carry DRM protection.
  • PRC: a format that we normally find in books from the People’s Republic of China and that is compatible with Kindle as long as it does not carry DRM protection.
  • TXT: flat and basic format, which you probably don’t usually find in ebooks but it can be useful if you have notes that you want to read on your Kindle.
  • PDF: Another of the formats supported by Kindle is PDF, although it may not be displayed on the device quite well due to the format of the text and images it contains.
  • Microsoft Word (DOC / DOCX): most DOC / DOCX files convert well into e-books. However, some complex format files may not convert as well.
  • HTML– Save your HTML file as a web page, filtered (HTM / HTML) (PC) or web page (HTM) (Mac). This will create a folder containing the HTML script along with the image files. Now, zip into a ZIP file before uploading to Kindle. If you don’t have images in your manuscript, you can upload the HTML file uncompressed into a ZIP file.
  • RTF: rich text format. It can be read on many programs and platforms and is easy to use.

If you have books in EPUB format and you want to read them on Kindle, we are sorry to tell you that they are not compatible. However, keep reading to find out how you can convert them into one of the compatible ones we just mentioned.

What is the best format to read on the Kindle?

The best format to read on Kindle is the AZW format, which is used for e-books that we buy from the Amazon Kindle Store. It is the preferred format to ensure maximum readability on the device. The format is proprietary and is actually a variant of the MOBI format, originally created by the French company Mobipocket.
