I’ve been uploading ebooks to Amazon for years, and the whole EPUB-to-MOBI conversion thing is a bit of a messy topic. Back in the day, Amazon’s Kindle Direct Publishing (KDP) only accepted MOBI files, so converting EPUB was a must. But things changed in 2022—Amazon phased out MOBI uploads for new titles and now prefers EPUB or KPF (Kindle Package Format) files. Here’s the kicker: if you convert an EPUB to MOBI yourself and upload it, Amazon’s system might still process it, but it’s not guaranteed. Their auto-conversion from EPUB usually works better than a pre-converted MOBI, especially since MOBI lacks some newer formatting features.
The real headache comes with older MOBI files. If you’re trying to publish a backlist title or update an existing book, Amazon might accept your MOBI, but it’s risky. I’ve seen cases where MOBI uploads get flagged for formatting issues that wouldn’t happen with EPUB. My advice? Skip the conversion step entirely and stick with EPUB. Amazon’s own conversion tools are surprisingly decent these days, and you’ll avoid weird font or layout glitches. Plus, EPUB supports stuff like fixed-layout children’s books or complex textbooks, which MOBI butchers.

Converting ebooks to Kindle format for Amazon is something I’ve done countless times, and it’s easier than you might think. The best tool for this is Calibre, a free and open-source ebook management software. After installing Calibre, simply import your ebook (EPUB, PDF, etc.) into the library. Then, select the book and click 'Convert Books.' Choose 'MOBI' or 'AZW3' as the output format—these are the formats Kindle supports. Calibre even lets you tweak metadata, fonts, and margins for a better reading experience.
Once converted, you can transfer the file to your Kindle via USB or email it to your Kindle’s unique email address (found in your Amazon account settings under 'Preferences'). Just make sure the email you send from is whitelisted in your Amazon account. If you’re dealing with DRM-protected books, you might need additional tools like DeDRM, but that’s a gray area legally. For most users, Calibre does the job perfectly without any hassle.

I can confirm Amazon does accept EPUB to MOBI conversions, but there's a catch. Amazon's Kindle Direct Publishing (KDP) platform prefers EPUB for uploads now, as MOBI is being phased out for newer Kindle features. However, if you have an older MOBI file, you can still upload it, but EPUB is the recommended format for better compatibility.
I've personally converted EPUB to MOBI using tools like Calibre, and it works seamlessly for personal use. But if you're publishing, stick to EPUB. Amazon’s conversion system handles EPUB files more efficiently, preserving formatting, fonts, and even complex layouts. For sideloading, MOBI works fine on older Kindles, but newer models like the Paperwhite or Oasis handle EPUB directly or through Amazon’s 'Send to Kindle' service, which auto-converts it to a Kindle-friendly format.

I can share my experience with file formats. Amazon’s Kindle Direct Publishing (KDP) platform primarily prefers files in .mobi format for Kindle devices, but they also accept .epub files now. However, if you convert an .epub to .mobi yourself, you need to ensure the formatting stays intact. Amazon’s own conversion system is quite robust, so uploading an .epub directly might be smoother.
I’ve tried both methods, and while manually converted .mobi files sometimes work, they can have formatting quirks like odd line breaks or misplaced images. Amazon’s system tends to handle .epub better these days, so I’d recommend uploading in that format and letting KDP convert it. Just make sure to preview your book thoroughly using their online viewer before publishing.

Converting PDFs to Kindle-friendly formats is something I’ve experimented with a lot, especially since I love reading on my Kindle. The easiest way is to use Amazon’s own 'Send to Kindle' service. You can email the PDF directly to your Kindle’s email address (found in your Amazon account settings) with the subject 'Convert'. Amazon will automatically convert it to a readable format. Alternatively, tools like Calibre are fantastic for more control. Calibre lets you convert PDFs to MOBI or AZW3, which are native Kindle formats. Just drag the PDF into Calibre, select 'Convert Books', and choose your desired format. One thing to note: PDFs with complex layouts might not convert perfectly, so it’s worth tweaking settings like margins or font size in Calibre for the best experience.
For those who prefer mobile solutions, apps like 'PocketBook' or 'Kindle App' itself can sometimes handle PDFs better than the e-reader. If you’re dealing with scanned PDFs (image-based), OCR tools like 'Adobe Acrobat' can extract text first, making conversion smoother. Lastly, if you’re tech-savvy, scripts like 'k2pdfopt' optimize PDFs specifically for Kindle screens by reflowing text. It’s a bit more involved but worth it for academic papers or manuals.

I can confidently say that Kindle does accept files converted from EPUB to PDF, but with some caveats. The Kindle ecosystem is primarily designed for Amazon's proprietary formats like AZW and MOBI, but it does support PDFs as well. The issue arises with the conversion process itself. EPUB is a reflowable format, meaning it adjusts text based on screen size, while PDFs are fixed-layout documents. Converting EPUB to PDF can sometimes result in awkward formatting, especially for complex layouts or images. I’ve tried this myself with a few novels, like 'The Name of the Wind,' and while the text remains readable, the experience isn’t as smooth as with native Kindle formats.
Another thing to consider is how you transfer the file. If you email the PDF to your Kindle address, Amazon will convert it again, which can lead to further formatting quirks. Directly sideloading via USB tends to preserve the original PDF layout better. For tech-savvy users, tools like Calibre can help optimize the conversion, but it’s still a bit of a gamble. If you’re dealing with a text-heavy book, the PDF might work fine, but for graphic novels or anything with intricate designs, you’re better off sticking to EPUB or using Amazon’s conversion service to MOBI. I’ve found that lightly formatted books, like 'Pride and Prejudice,' fare better in PDF, while something like 'Sandman' would be a nightmare.

Converting PDFs to Kindle-friendly formats like MOBI or AZW3 is something I do all the time because I love reading on my Kindle. The easiest way is to use Amazon’s free 'Send to Kindle' service, which lets you email the PDF directly to your Kindle address. Just attach the file, set the subject to 'convert,' and Amazon handles the rest. It’s super convenient, though the formatting might not always be perfect, especially for complex PDFs with lots of images or tables.
For more control, I recommend using Calibre, a free ebook management tool. It’s a bit more hands-on but gives better results. Just import the PDF into Calibre, convert it to MOBI or AZW3, and then transfer it to your Kindle via USB or email. Calibre also lets you tweak settings like margins and fonts, which is great for optimizing readability. If you’re dealing with scanned PDFs, OCR software like Adobe Acrobat or online tools can help extract text first, but it’s a bit more work.

Amazon's Kindle Direct Publishing (KDP) platform is pretty specific about file formats. They don’t directly accept PDF-to-MOBI conversions anymore because MOBI is outdated for new uploads. Amazon phased out MOBI support in favor of EPUB and KPF formats. If you upload a MOBI file, it’ll still work for older Kindle devices, but you’re better off converting your PDF to EPUB first. Calibre is a lifesaver for this—it’s free, easy to use, and handles conversions cleanly.
One thing to watch out for is formatting. PDFs are rigid, so text and images might get messy during conversion. EPUB fixes this by reflowing content, making it adaptable for different screen sizes. Amazon’s own conversion tool can sometimes butcher complex layouts, so I always recommend tweaking the EPUB manually before uploading. If you’re publishing, stick to EPUB; if it’s for personal use, MOBI works but isn’t future-proof.

the file conversion question pops up a lot. Kindle does support TXT files, but converting them to PDF isn't straightforward within the ecosystem. The Kindle's native system prioritizes formats like MOBI or AZW for optimal reading. PDFs work, but they're rigid—text doesn't reflow, and zooming on smaller screens is a hassle. I tried sideloading a TXT-converted PDF via USB, and while it displayed, the formatting was messy. Calibre, a third-party tool, is a lifesaver here. It converts TXT to PDF (or better yet, MOBI) while preserving structure. Amazon's email-to-Kindle service also accepts TXT, but auto-converts it to their proprietary format, not PDF.
For heavy readers, relying on PDFs from TXT feels like wearing gloves to handle delicate pages—it works, but isn't ideal. EPUB (now supported by Kindle) or MOBI conversions retain more flexibility. The takeaway? Kindle 'accepts' TXT-to-PDF in the same way a car 'accepts' square wheels—technically yes, but you'll feel every bump.

their PDF-to-Kindle conversion is a mixed bag. The service exists, but it's not perfect—some formatting gets mangled, especially complex layouts or custom fonts. I always recommend converting to EPUB first using tools like Calibre for better results. Amazon's system tends to strip out certain elements that matter to authors, like drop caps or specific spacing.
The real kicker is how it handles images. PDFs with heavy graphics often come out pixelated or misaligned on Kindle devices. I learned this the hard way with my first art book. Now I use Kindle Create or hire a formatter for anything visually complex. Amazon's auto-conversion works fine for text-heavy novels, but for anything beyond basic prose, you'll need extra steps to maintain quality.
