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.

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 confirm that Amazon Kindle does support converting PDF to MOBI, but it's not as straightforward as you might hope. The Kindle Personal Documents Service allows you to email PDFs to your Kindle address, and Amazon will convert them to MOBI format automatically. However, the conversion quality varies—some PDFs with complex layouts or images might not translate well.
I've found that using third-party tools like Calibre often gives better results for PDF-to-MOBI conversion. Amazon's system works best with simple text-heavy PDFs. Remember to include 'convert' in the email subject line when sending documents to your Kindle email address. For important documents, I always double-check the converted file on my Kindle before relying on it.

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.

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've tried converting mobi files to pdf for personal use. Amazon doesn't provide a direct tool to convert mobi to pdf, but you can use third-party software like Calibre to do it. I often convert books I own to pdf so I can read them on devices that don't support mobi. Just make sure you only convert books you've purchased and don't share them, as that would violate copyright laws. It's a handy workaround if you need your books in a different format for convenience.

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.

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.

I can confirm that Amazon does not legally allow the conversion of MOBI to EPUB if the file is DRM-protected. Amazon’s Kindle ecosystem primarily uses MOBI or its newer formats like KFX for DRM-protected books. Removing DRM to convert the file violates their terms of service. However, if the MOBI file is DRM-free (like public domain books or those from authors/publishers who distribute without DRM), you can legally convert it using tools like Calibre. Always check the book’s DRM status before attempting any conversion to stay compliant with copyright laws.

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.
