I've been using Kindle for years, and it supports a variety of ebook formats, which makes it super convenient for readers like me. The primary format is Amazon's proprietary '.azw' and '.azw3', which are optimized for Kindle devices. They also support '.mobi', though newer versions are phasing it out. If you sideload books, '.pdf' works, but the experience isn't as smooth as with native Kindle formats. For flexibility, I often convert files to '.epub' using tools like Calibre since Amazon now accepts '.epub' for email transfers. Plain text files ('.txt') and '.html' are also supported, but they lack formatting. Always check the file type before downloading to avoid compatibility issues.

I’ve explored every possible format to make sure my library stays versatile. The Kindle supports MOBI and AZW formats natively, which are perfect for direct downloads from Amazon. However, if you’re sideloading books, EPUB is now supported too, thanks to recent updates—just send it via the 'Send to Kindle' email or app. PDFs work but aren’t ideal for reflowing text, so I usually convert them.
For older Kindles, PRC files also work, though they’re less common now. If you’re into fan translations or indie books, TXT files are a lifesaver, but formatting can be messy. I’ve also used KFX for enhanced typesetting, but it’s trickier to sideload. Calibre is my go-to tool for converting unsupported formats like DOCX or HTML into Kindle-friendly ones. The key is to stick with MOBI, AZW, or EPUB for the smoothest experience.

I’ve experimented with countless file formats and can confidently share what works best. The native format for Kindle is MOBI, but Amazon has shifted towards AZW and AZW3 for newer models, which support advanced features like custom fonts and layouts. EPUB, while widely used elsewhere, isn’t directly compatible unless you convert it using tools like Calibre or Amazon’s Send-to-Kindle service. PDFs can be read but often lack reflowability, making them clunky for smaller screens.
For manga or graphic novels, CBZ and CBR files are surprisingly well-supported, though they’re better suited to larger screens like the Kindle Fire. Plain text (TXT) and HTML files also work in a pinch, but they’re barebones. If you’re sideloading, KFX is the gold standard for typography and formatting, but it’s trickier to generate. Personally, I stick to AZW3 for novels and convert everything else using Calibre—it’s a lifesaver for organizing my digital library.

I’ve explored every nook and cranny of its supported formats. The most common and widely compatible format is MOBI, which has been a staple for Kindle users. However, Amazon has been transitioning to EPUB support, which is fantastic because EPUB is the industry standard for e-books. PDFs are also supported, but they don’t always display well due to their fixed layout.
For those who love customization, AZW and AZW3 formats are great because they retain advanced formatting like fonts and images. If you’re into fan translations or indie books, TXT files work too, though they lack formatting. Lastly, KFX is the newest format, offering enhanced typesetting and features, but it’s not as universally compatible. Always check the file type before downloading to ensure a smooth reading experience!

I’ve been using my Kindle for years, and it’s wild how many formats it can handle! The main ones are MOBI and AZW, which are Amazon’s proprietary formats, but it also supports PDF, TXT, and even HTML. EPUB is a bit tricky—Kindles don’t natively support it, but you can convert EPUB files using tools like Calibre, which I’ve done a ton. I love how versatile it is for reading fan-translated novels or academic papers in PDF.
One thing I wish more people knew is that Kindle also supports DOCX and RTF, so you can drag and drop documents from Word without fuss. Comic fans might be disappointed, though—CBZ and CBR files won’t work unless you convert them. Still, for a device focused on books, it’s pretty flexible. I’ve even loaded up public domain books in plain TXT when I’m in a minimalist mood.

Kindle's been my go-to for years, and I love how flexible it is with file formats. The main ones it supports natively are MOBI (though newer Kindle models are phasing this out), AZW, AZW3, and KFX—those are Amazon's proprietary formats. But here's the cool part: it also handles PDFs, though the reading experience isn't as smooth since you can't adjust fonts or layouts much. TXT files work too, but they lose formatting.
For EPUB, there's a catch—Kindle doesn't support it directly, but you can convert EPUBs using Amazon's free Send to Kindle service or tools like Calibre. I've converted dozens of EPUBs this way, and it's seamless. HTML works in a pinch, and even DOC/DOCX files can be sideloaded. Honestly, the only major format I wish they'd add native support for is CBZ/CBR for comics, but third-party converters bridge that gap.
