Good to know

How do I convert MOBI to EPUB online?

Choose a DRM-free MOBI file, review the conversion options, then select Convert Now. Download the EPUB and check the text in your reading app before removing the original.

Are my books uploaded to a server?

Files you choose from your device are processed locally in your browser. Conversion does not upload their contents to our server. Importing a book from a URL contacts the website hosting that file.

Can I convert a DRM-protected Kindle book?

No. Encrypted books are not supported. Use a DRM-free copy you are allowed to convert; changing the filename does not remove encryption.

Will the EPUB keep the original formatting?

Results depend on the source book. This converter extracts text and builds an EPUB; complex layouts, illustrations, covers and fonts may not be preserved. Check the downloaded book and keep the original.

How do I send the EPUB to my Kindle?

Use Amazon Send to Kindle to submit the EPUB. Amazon converts supported documents for your Kindle library. Copying an EPUB directly to a Kindle by USB is a different workflow and does not make it a native Kindle book.

When should I use Calibre instead?

Calibre is useful for managing a desktop ebook library and inspecting conversion settings. Try it when this browser converter cannot read your file, or when you need more control over the result.

URL imports contact the file's host. Sending a file to Kindle is a separate upload to Amazon.

MOBI and EPUB: what changes?

MOBI is associated with older Kindle and Mobipocket books. EPUB packages text, styles and other resources for compatible reading apps. This converter extracts readable text and builds a new EPUB. Complex layouts, covers, illustrations and fonts may not be preserved.

More eBook tools

More ways to prepare your books, using the tools already available on MobiToEpub. These additional tools currently use English.

EPUB package checks

Inspect common EPUB packaging issues and download supported repairs. This is a basic check, not EPUBCheck or Kindle certification.

Cover designer

Create a cover with your title, author and artwork. Download a JPEG, or apply it to the first unconverted book in your queue.

Comic to EPUB

Open CBZ, ZIP or image files, create a fixed-layout comic and download an EPUB. CBR/RAR is not supported. Check the result in your reader.

Image dithering

Adjust grayscale, contrast and dithering in an image. Download a PNG, or use it as a queued book’s cover.

File & hash inspector

View a file’s header bytes, calculate its hash and export a report. A hash identifies bytes; it does not prove who created a file.

Manuscript & field notes

Enhance a scanned image and write your own transcription and research notes. Export Markdown or TEI XML; text recognition is manual.
