Why use this tool
The book never leaves your device
It all happens in your browser. Your books are not uploaded to any server, not even ours.
With a real table of contents
The MOBI carries a proper contents list with links to each chapter — that is what the Kindle uses to move through a book.
With the cover
The EPUB cover becomes the MOBI cover, so it shows up in the reader's library.
Nothing to install
No Calibre, no software: it happens on the page itself, in seconds.
Frequently asked questions
Does it work on any Kindle?
MOBI is the Kindle's long-standing format and every model opens it. The newest ones also read EPUB directly, so if yours is recent you may not need to convert at all.
What about books bought from Amazon?
Books with store DRM cannot be converted: they are encrypted and need the seller's key. This tool works with unprotected books — your own, public-domain ones, or DRM-free purchases.
Is the EPUB's design kept?
Text, headings, lists, images and cover, yes. Fonts and fine styling, no: the MOBI format is far simpler than EPUB and has no room for them. That is a limit of the format, not of the tool.
Is there a size limit?
Only your browser's. Multi-megabyte books with images convert in seconds.
What if my file is AZW3?
AZW3 is the newer Kindle format. To turn it into EPUB use the MOBI to EPUB tool, which opens the ones that carry the classic MOBI part inside.
