I can tell you that Amazon doesn't support the MOBI format for new uploads anymore. They phased it out in favor of EPUB and KPF formats. If you have an older MOBI file, you might still be able to use it, but EPUB is the way to go for new submissions. The switch makes sense because EPUB is more versatile and widely supported. I remember trying to upload a MOBI file last year and getting a prompt to convert it. Amazon’s Kindle Direct Publishing platform has tools to help with the conversion, so it’s not a huge hassle. Just make sure your formatting stays intact during the process.

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.

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.

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 They don’t directly accept PDF-to-MOBI conversions anymore because MOBI is outdated for new uploads.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 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.

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'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 confidently say that converting MOBI to PDF for personal use is generally legal if you own the book. The key is whether you redistribute or profit from the converted file. I've converted dozens of my own manuscripts to PDF for formatting checks, and it's no different than printing a personal copy. Just remember, sharing that PDF publicly or selling it crosses into piracy territory. Amazon's terms even allow format shifting for personal backups. But always check the specific book's copyright page—some indie authors explicitly prohibit conversions.
If you're unsure, reaching out to the author directly is the safest bet. Many self-published creators are approachable via social media or email.

I can tell you that finding a mobi/pdf converter that plays nice with novel publishers is tricky. Most mainstream tools like Calibre are great for personal use but lack the precision formatting and DRM flexibility that publishers need. The real industry standard is Vellum, though it's Mac-only and pricey. It creates gorgeous, publisher-ready files with perfect chapter breaks, drop caps, and consistent spacing—things that matter when you're dealing with 100k-word manuscripts.
For Windows users, Jutoh is a solid alternative with similar features but less polish. It handles complex layouts better than Calibre and exports clean mobi files that don't break on Kindle devices. Some indie publishers swear by Atticus too—it's web-based and has collaboration features perfect for editorial teams. The key is avoiding converters that strip metadata or mangle formatting. Publishers care about things like preserving the author's original typography quirks or embedding correct ISBNs, which free tools often butcher.

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.
