EPUB to MOBI Converter

Convert EPUB to MOBI directly on your Android device. Preview three pages of content, review validation notes and choose how to prepare the file before exporting.

EPUB to MOBI is a focused converter for readers who want a private process that is easy to follow. Conversion runs locally, so your books are not sent to a server and you can work without an internet connection.

How to convert EPUB to MOBI

1. Select one or multiple EPUB files.
2. Review the book metadata.
3. Adjust output options when needed.
4. Follow the conversion progress.
5. Check the preview and validation notes.

Preview before exporting

Every conversion creates an integrated three-page preview. It lets you check the EPUB content used to build the MOBI. Final appearance may vary depending on the e-reader or Kindle device.

Book metadata and output options

Edit the title, author, language, publisher, series and series number before converting. You can also choose compatibility for classic Kindle devices or a smaller modern MOBI. Advanced options control text compression, image quality, inclusion of the original EPUB and embedded book fonts.

Batch conversion with clear progress

Add multiple EPUB files to the queue and see the status of each book during reading, validation, MOBI creation and finalization. If a file contains issues, the app separates non-blocking validation errors from warnings to help explain possible differences in the result.

Private conversion and storage controls

Book content, filenames, authors and file paths are not sent to conversion servers. Settings lets you remove the cache, history and previously generated files without deleting original EPUB files or copies exported outside the app.

Conversion, preview and Premium

You can convert EPUB to MOBI and review the preview before deciding whether you need Premium. Premium unlocks saving MOBI files, sharing them with other apps and keeping conversion history. Weekly, monthly and annual subscriptions are available; introductory trial availability depends on eligibility confirmed by Google Play.

DRM-protected EPUB files cannot be converted because their content is encrypted. Use the app only with books you own or files you have the right to convert.
