* MOBI (Mobipocket): This was the original Kindle format, and while still supported, it's less common now.
* AZW (Amazon Kindle Format): This is the most common format for Kindle books. It's a proprietary format optimized for Kindle devices.
* AZW3 (Amazon Kindle Format 8): This is a newer and more advanced version of the AZW format, offering better compression and features.
* KFX (Kindle Format 9): This is the latest Kindle format, designed for improved performance and responsiveness.
* EPUB (Electronic Publication): This is an open standard format supported by many e-readers and platforms. Kindle devices can open EPUB files, but they may not always render them correctly.
Additional Notes:
* While Kindle devices can handle other formats like PDF, they aren't ideal for reading on a Kindle due to layout issues and potential for poor formatting.
* You can convert files to Kindle-compatible formats using software like Calibre.
For the best reading experience on a Kindle, stick to MOBI, AZW, AZW3, or KFX formats.
