I've found that the most common supported formats are MOBI and AZW. These are Amazon's proprietary formats, and they work seamlessly. EPUB is another popular format, but Kindle doesn't natively support it unless you convert it using tools like Calibre. PDFs can also be read, but the formatting often gets messy, especially on smaller screens. For public domain books, I often use Project Gutenberg, which offers MOBI files directly. If you’re into fan translations or indie works, TXT files are a simple option, though they lack formatting. Just make sure to check the file type before downloading to avoid frustration.

I can confidently say that many websites do support Kindle formats, but it depends on where you look. Sites like Project Gutenberg and Open Library offer classics and public domain books in MOBI or AZW formats, which are Kindle-friendly. You just download the file and transfer it via USB or email it to your Kindle address. Some newer sites might only offer EPUB, but you can easily convert those using free tools like Calibre. I’ve built quite a collection this way without spending a dime, and it’s perfect for my old Kindle Paperwhite.

I've experimented with tons of formats and found the best ones for free novels. MOBI and AZW3 are the classics, perfectly optimized for Kindle's e-ink display, preserving formatting and allowing adjustable fonts. But lately, I’ve been loving EPUB—since Amazon started supporting it natively, it’s become my go-to for its versatility and crisp layout.
For public domain books, PDFs can work if formatted well, but they often lack reflowability, making them clunky on smaller screens. Plain TXT files are great for lightweight reads, though they miss out on rich formatting. If you’re into fan translations or niche web novels, HTML or KFX formats can sometimes offer better customization. Calibre is a lifesaver for converting between formats without losing quality.

I've found a few reliable sites that offer Kindle-compatible formats for free. Project Gutenberg is a classic choice with over 60,000 free ebooks, mostly classics, available in MOBI format which works perfectly on Kindle. Another favorite of mine is ManyBooks, which has a sleek interface and lets you filter by Kindle-friendly formats like MOBI and AZW3.
For more contemporary reads, I often turn to Open Library where you can borrow modern ebooks in Kindle format just like a digital library. The Internet Archive also has a massive collection where you can find EPUBs that convert easily to Kindle formats using free tools like Calibre. What I appreciate about these sites is they're all legal and safe, unlike some shady ebook torrent sites that might get your device infected with malware.

Can we take a second to appreciate that all this is even possible? We're talking about instantly getting thousands of free, classic novels onto a device we carry in one hand. The format hassle is a tiny price to pay for that magic.
I remember hunting through used bookstores for out-of-print titles. Now I can get 'Moby-Dick,' 'Pride and Prejudice,' and tons of lesser-known classics in seconds, for free, in a format that lets me adjust the font size. It's amazing.
So while we debate .azw3 vs. EPUB, the real winner is digital accessibility itself. Any format that gets you reading is a good format.

I've explored numerous free online libraries that support Kindle formats. Project Gutenberg is a classic choice, offering over 60,000 free ebooks, many in Kindle-friendly formats like MOBI. You can download directly or email the file to your Kindle.
Another fantastic resource is Open Library, which provides borrowable Kindle books (EPUB or MOBI) through controlled digital lending. Their collection is vast, ranging from classics to contemporary works. Just check the format before borrowing—some require conversion via tools like Calibre.
For public domain books, ManyBooks is a gem. It categorizes titles neatly and offers multiple formats, including MOBI for Kindle. Their user interface is clean, making downloads effortless. Lastly, Feedbooks has a solid selection of free Kindle-compatible books, especially in genres like romance and sci-fi. These sites are lifesavers for budget-conscious readers who love their Kindles.

Kindle's compatibility with free e-reader formats is a bit of a mixed bag, and I've had my fair share of trial and error with it. While it natively supports formats like MOBI (older versions) and AZW, EPUB—the most common free ebook format—isn’t directly compatible. But here’s the kicker: Amazon’s 'Send to Kindle' feature now accepts EPUBs, converting them automatically. I used it recently for a public domain classic from Project Gutenberg, and it worked flawlessly.
For other formats like PDF, Kindle can handle them, but the experience isn’t as smooth. Text reflow is hit-or-miss, and scanned PDFs are a nightmare. Calibre is my go-to tool for converting non-native formats like TXT or HTML into Kindle-friendly ones. It’s a bit nerdy, but once you get the hang of it, your ebook library becomes way more versatile. Honestly, the Kindle ecosystem feels a tad restrictive, but with a little workaround savvy, you can make it play nice with almost anything.

Publishing a novel in Kindle-supported format is easier than you might think, and I’ve gone through the process myself. The first step is to format your manuscript properly. Kindle Direct Publishing (KDP) accepts files in .doc, .docx, or .epub formats, but I highly recommend using .epub for the best results. Tools like Calibre or Kindle Previewer can help you convert and check your file before uploading.
Once your file is ready, create an account on KDP’s website. You’ll need to fill in details like your book’s title, description, and keywords. Choosing the right categories and keywords is crucial for visibility. After that, upload your manuscript and cover. KDP offers a cover creator tool if you don’t have one, but a professional design works best. Finally, set your price and royalty options, and hit publish. It usually takes up to 72 hours for your book to go live.

I love how versatile it is when it comes to file formats. The best format is definitely MOBI, which is Amazon's proprietary format designed specifically for Kindle devices. It supports features like bookmarks, highlights, and notes seamlessly. AZW and AZW3 are also great, especially for books purchased from Amazon, as they retain formatting and DRM protection.
For more flexibility, EPUB is a widely used format, but Kindle doesn't natively support it. You can convert EPUB to MOBI using tools like Calibre, which I highly recommend. PDFs work too, but they don’t reflow text well on smaller screens, making them less ideal for novels. TXT files are simple and compatible, but lack formatting. HTML and DOCX can also be sideloaded, though they might need conversion for optimal reading. If you’re into comics or illustrated novels, CBZ and CBR are supported, but they’re better suited for graphic-heavy content.
