How to convert MOBI to EPUB

  1. Add your MOBI e-books

    Drop MOBI files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.

  2. EPUB is already chosen

    Press Convert and confirm the upload. The file is sent to the ToAny conversion server, converted to EPUB and removed afterwards.

  3. Download

    Save the EPUB, or download everything as one ZIP if you converted several files.

Why ToAny

  • Honest about uploads

    Browsers cannot convert MOBI to EPUB reliably, so this pair runs on our server. You are asked before anything is sent, and the page says so plainly.

  • Removed afterwards

    The uploaded file and the result are deleted once the conversion has finished. Nobody looks at them and they are not used for anything else.

  • No account

    No sign-up, no email address and no watermark on the result.

MOBI to EPUB: what to expect

MOBI is no longer accepted by Send to Kindle and is not opened by other e-readers. EPUB reflows to fit any screen and opens in most e-reader apps. MOBI is at home in Kindles too old for newer formats; EPUB is the usual choice for e-books that adapt to any screen size.

MOBI vs EPUB

MOBI

Kindle e-book

MOBI is the e-book format older Kindles used. Amazon stopped accepting MOBI through Send to Kindle in 2022 in favour of EPUB, so it is now mostly found in old libraries.

Opens in Older Kindles and Calibre

EPUB

EPUB e-book

EPUB is the open standard for e-books. Text reflows to fit the screen and the reader chooses the font and size. Almost every e-reader other than older Kindles opens it directly.

Opens in Apple Books, Kobo, Google Play Books, Calibre and, since 2022, Send to Kindle

Questions

Is my MOBI file uploaded?

Yes, for this conversion. Browsers cannot convert MOBI to EPUB reliably, so after you confirm, the file is uploaded over an encrypted connection to the ToAny conversion server, converted automatically and deleted once the conversion has finished. Most other conversions on ToAny run in your browser and upload nothing.

Is anything lost when converting MOBI to EPUB?

Text is kept. Formatting carries over only as far as EPUB supports it.

Can I convert several MOBI files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert MOBI to EPUB on Windows, Mac, iPhone or Android?

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the MOBI file, press Convert and save the EPUB. There is nothing to install.

Is there a file size limit?

Yes. Files sent to the conversion server are capped in size, and the page tells you when a file is too large to upload.
