EPUB to MOBI Converter — Free Online
Processed on our servers — auto-deleted within 1 hour, never used for anything else.
Bought a book in one store and want to read it on another device? Converting EPUB to MOBI frees your library from any single app or shop. Upload your DRM-free epub file, our servers convert it with a professional ebook engine, — delete both files right after processing, or let them auto-delete within the hour.

About this tool
EPUB to MOBI, without the desktop detour
Upload your DRM-free EPUB, and our servers re-render the book for MOBI readers — older Kindle devices and apps that never adopted the newer formats. Both files are deleted automatically within the hour, or delete them yourself with one click right after the conversion.
Why MOBI still matters
MOBI is the format of older Kindle hardware and some reading apps that never moved on. If your e-reader predates AZW3 support or a recipient's device expects it, converting from EPUB is the bridge — typography re-renders for the target format automatically.
What converts and what needs checking
Text, chapters, and structure convert cleanly; DRM-protected books are refused by design. Complex tables and image-heavy layouts may shift between formats — glance at the result before loading it onto the reader.
Frequently asked questions
Why does my store-bought book fail to convert?
Most store books carry DRM protection, which this tool does not remove — removing it is circumvention. DRM-free EPUBs convert perfectly; books exported from a desktop library app usually work too.
Do images and covers survive the conversion?
Embedded images and cover art carry over, though the MOBI format constrains image handling more than EPUB — heavily illustrated books may need a look at the result.
Is my book uploaded to a server?
Yes — MOBI conversion runs on our servers, and both the original and the converted file are deleted automatically within one hour. Nothing is kept, shared, or used for anything else.
