What Filee does for MOBI → EPUB
Move an old Kindle/Mobipocket library to EPUB so it opens in Apple Books, Google Play Books, Kobo and most reader apps. This direction is built in, so Calibre isn't needed.
- Built in: works right after installing Filee, with nothing else to download.
- Works with DRM-free books only.
- Batch: one file or hundreds, converted in parallel; a failure never stops the rest.
- Private: files are converted on your PC and never uploaded, even without internet.
- Saved next to the original, or in a folder and with a file name pattern you choose.
MOBI can also become
- DOCX
- TXT
- HTML
- HWPX
