I can confirm that it does support the .mobi format, but there's a catch. Amazon has been gradually shifting toward newer formats like .azw3 and .kfx, which offer better features like enhanced typography and layout. Mobi files are still readable on most Kindle devices, but some newer features might not be fully supported.
If you're downloading books directly from Kindle Unlimited, they usually come in a compatible format for your device. However, if you have personal .mobi files you want to upload via Send to Kindle, they’ll still work, though Amazon recommends converting them to EPUB for better compatibility. The Kindle ecosystem is evolving, so while .mobi isn’t going away overnight, it’s worth keeping an eye on updates.

the shift away from MOBI has been one of the most significant changes. Remember when MOBI was the golden standard for Kindle? Those days are long gone. Amazon officially stopped supporting new MOBI uploads in 2022, which hit a lot of indie authors like a ton of bricks. The company's pushing hard for KPF (Kindle Package Format) now, which honestly offers better typography and layout options.
What's wild is how many people still try uploading MOBI files out of habit. The Kindle Direct Publishing platform straight-up rejects them with a message nudging you toward EPUB. It's not just about file formats—this reflects Amazon's strategy to control the entire ebook ecosystem. EPUB gives them more flexibility to enforce DRM and standardize the reading experience across devices. For us readers, the transition's mostly invisible, but for authors, it's been a headache requiring complete workflow overhauls.

I can confidently say that MOBI files are still compatible with older Kindle models, but there’s a catch. Amazon has shifted its focus to the newer AZW3 and KFX formats, which offer better features like enhanced typography and layout. While you can sideload MOBI files via USB, they won’t sync across devices using Whispersync.
For newer Kindle models, I recommend converting MOBI to AZW3 or EPUB (which Kindle now supports) using tools like Calibre. This ensures you get the best reading experience with features like font customization and page flipping. If you’re nostalgic for MOBI, it still works, but the future is definitely leaning toward more advanced formats.

I can tell you Amazon's stance on formats has shifted over time. They used to accept MOBI files directly, but now they prefer EPUB for new uploads. The reason behind this change is EPUB's wider industry adoption and better compatibility with modern features like reflowable text and advanced formatting. When you upload an EPUB to Kindle Direct Publishing, their system automatically converts it to their proprietary KFX or AZW3 formats.
Interestingly, you can still sideload MOBI files to your Kindle device via email or USB, but Amazon no longer recommends this for publishing. The conversion from EPUB usually works well, though complex layouts might need tweaking. It's always worth checking the previewer tool after upload to catch any formatting oddities. Amazon provides detailed guidelines on their help pages about preparing EPUB files for the best results.
For technical users, it's noteworthy that Amazon's conversion preserves most standard EPUB features, including tables of contents and basic styling. However, fixed-layout books and complex typography might require special handling. Many authors use tools like Kindle Previewer to test their files before submission. The shift from MOBI to EPUB reflects broader industry trends toward standardization, making life easier for readers who use multiple platforms.

I can confidently say Mobi files aren’t the best fit for Kobo devices. While Kobos primarily support EPUB and PDF formats, Mobi files can sometimes work if they’re DRM-free, but the experience isn’t seamless. Amazon’s Mobi format is optimized for Kindle, so features like font customization or layout adjustments might not translate well to Kobo.
If you’re committed to using Mobi files on a Kobo, converting them to EPUB via tools like Calibre is a smarter move. Kobos handle EPUB flawlessly, preserving formatting and enhancing readability. I’ve tested this myself with classics like 'Pride and Prejudice' and modern reads like 'The Silent Patient,' and the difference is night and day. For tech-savvy readers, sideloading converted files is straightforward, but casual users might find it tedious. Stick to EPUB or Kobo’s native store for hassle-free reading.

the whole conversion thing can be a bit of a maze. Amazon does support converting files to MOBI, but it's not as straightforward as it used to be. Back in the day, you could email a document to your Kindle address, and it would automatically convert to MOBI. Now, Amazon has shifted focus to their newer format, AZW3, but MOBI still works for most older Kindle devices. The trick is to use the 'Send to Kindle' feature or the Kindle Personal Documents Service. Just make sure your file isn't DRM-protected, or it won't convert.
One thing that bugs me is the lack of clarity from Amazon about which formats are fully supported. MOBI files can still be sideloaded via USB, but they won't sync across devices like AZW3 or KFX files do. If you're using Calibre, you can manually convert to MOBI, but the formatting might get wonky. Amazon’s support pages are a bit vague, but from my experience, MOBI conversion is hanging on by a thread—functional but not future-proof.

it's been a game-changer. The device supports formats like CBZ, CBR for manga, and MOBI, AZW, PDF for novels. The screen is decent for black-and-white manga, though color pages can look a bit dull. For novels, the text is crisp, and the adjustable font size is a lifesaver for long reading sessions. I personally love how lightweight it is—perfect for binge-reading 'Attack on Titan' or 'One Piece' without straining my arms. The Kindle store also has a solid selection of manga and light novels, though sideloading via USB or email works seamlessly too.

I can confirm that Amazon does sell novels in both epub and mobi formats, but with a few caveats. Kindle devices and apps primarily use mobi and the newer KFX formats, but Amazon has started supporting epub as well for sending documents to your Kindle library. However, when you purchase ebooks directly from Amazon, they usually default to their proprietary AZW format.
If you prefer epub, you might need to use third-party tools to convert the files, though Amazon’s 'Send to Kindle' feature now accepts epub uploads. For mobi, it’s more straightforward since Kindle’s ecosystem is built around it. If you’re looking for a wide selection, Amazon’s store is a great place, but always check the format details before purchasing to avoid surprises. Some indie authors also offer direct epub downloads, so keep an eye out for those options.

I recently got the latest Kindle Fire. It doesn't natively support EPUB format, which can be a bummer if you have a lot of EPUB files. Amazon uses its own formats like AZW or MOBI. But there are workarounds—I usually convert EPUB files to MOBI or AZW3 using Calibre, a free ebook management tool. The conversion process is pretty straightforward, and the books look great on the Kindle Fire. Another option is sending the EPUB to your Kindle email with 'Convert' in the subject line, and Amazon will convert it for you. It's not perfect, but it gets the job done.

I can confidently say that while Kindle devices primarily support MOBI files, you can indeed read EPUBs on them—but with a tiny catch. Amazon recently phased out direct EPUB support, but you can convert EPUB to MOBI or the newer Kindle-friendly format (AZW3 or KFX) using tools like Calibre or Amazon’s Send-to-Kindle service.
I’ve personally converted dozens of EPUBs to MOBI, and they work flawlessly on my Kindle Paperwhite. The formatting stays intact, and the reading experience is seamless. Just drag and drop the converted file via USB or email it to your Kindle address. If you’re tech-savvy, Calibre even lets you tweak fonts and margins for a customized feel. For cloud-based convenience, Send-to-Kindle automatically converts EPUBs during upload, though it skips some complex layouts.
