The book is read and converted in your browser: no upload, no account, no watermark. DRM-protected books are refused: no protection is ever bypassed.
EPUB, MOBI, AZW3, FB2: ebook formats explained
EPUB is the open ebook format: Kobo, Apple Books, Google Play Books, Nook and most reading apps open it, and Amazon has accepted it through Send to Kindle since 2022. MOBI and AZW3 are Amazon's older Kindle formats: MOBI goes back to Mobipocket, and AZW3 (or KF8) is its more modern version. FB2, or FictionBook, is very popular in Russia and Eastern Europe, with e-readers like PocketBook and the FBReader app. This converter reads all of these formats and produces an EPUB, an FB2, a book-style PDF, a Word document, an HTML page or plain text.
Getting a book onto your Kindle or Kobo
For a Kindle, convert your book to EPUB, then send it with Send to Kindle: by email to your Kindle address, from the Kindle app on your phone, or from Amazon's website. Amazon converts it to its own format, with the cover and table of contents. For a Kobo or a PocketBook, plug the e-reader into your computer and simply copy the EPUB file to its storage. On iPhone and iPad, open the EPUB with Apple Books. An old MOBI that Send to Kindle no longer accepts becomes readable again once it's converted to EPUB.
Turn a Word document or a PDF into an EPUB
Wrote a novel, a thesis or a guide in Word? Drop the .docx file: each chapter heading becomes an EPUB chapter, with a clickable table of contents, images and basic formatting (bold, italic, lists, tables). Add a cover and the author's name, and the book is ready for an e-reader or for self-publishing. A text file is split at lines like "Chapter 1", "Chapter 2"… From a PDF, the text is rebuilt to reflow to the e-reader's screen size, which is far more comfortable than the original PDF, but the images and layout are not carried over.
DRM-protected books and limitations
Books bought from most online stores (Amazon, Kobo, Apple Books…) are often locked with DRM, a digital protection. This converter detects them and refuses them: it does not bypass any protection. It works with DRM-free books, such as public-domain classics, books sold "DRM-free" or your own writing. Fixed-layout books (comics, illustrated books) are converted to reflowable text, which can move images around. Finally, the tool does not produce MOBI or AZW3: Send to Kindle no longer accepts these formats and prefers EPUB.
Frequently Asked Questions
How do I put an EPUB on my Kindle?
Use Amazon's Send to Kindle: email the EPUB to your Kindle address (shown in the e-reader's settings), or drag it onto the Send to Kindle page on Amazon's website. The book shows up on your Kindle a few minutes later.
Why is there no MOBI or AZW3 output?
Amazon stopped accepting MOBI in Send to Kindle in 2022 and recommends EPUB, which it converts for the Kindle itself. So convert your MOBI or AZW3 to EPUB: it's the format that works everywhere.
Can I convert a book I bought on Amazon or Kobo?
Only if it's sold DRM-free. DRM-locked books are refused with a clear message: the tool doesn't bypass any protection.
How is this different from the EPUB to PDF tool?
EPUB to PDF is specialized in that one conversion, with more print settings (text size, margins). This converter reads many formats (MOBI, AZW3, FB2, Word, PDF…) and produces EPUB, PDF, FB2, Word, HTML or text.
How do I change an EPUB's cover?
Drop the EPUB, tap "Change cover" and pick an image (JPG, PNG, WebP…), then convert to EPUB: you get the same book with the new cover. The title and author can be fixed the same way.
Is my book uploaded to the internet?
No. The book is read and converted by your browser, on your device. No file is sent to Chatzam or any other service.
