How it works
Choose your MOBI files or drop them on this page.
Press Convert to EPUB. Chapters, readable text, headings and supported pictures are kept for your EPUB reader.
Download one EPUB for each file. The result says how many chapters and pictures were kept, or if pictures were left out.
Questions
Are my books uploaded anywhere?
No. The work happens inside this browser tab, so your books never leave your device and no server sees them. Closing the tab clears them from memory.
What does the copy keep?
Chapters, readable text, headings and supported pictures are kept for your EPUB reader. DRM-protected books refuse with a message. KF8 and older MOBI books work, including .prc and .azw files.
What are the limits?
Up to 100 files per run, each up to 64 MB. The shared engine may refuse a book that is too complex or takes too long. Your original files stay unchanged.
The same file engine is in the UFO apps for Android and Windows.
