Book Batcher

No upload · Your books are opened, converted and saved by this tab alone

A bindery for the books you already own.

Drop in EPUB, MOBI, AZW3 or comic archives and get back the format your reader wants. Assemble a folder of scans into a book. Fix a cover, repair a broken package, or read the result before you send it anywhere. None of it is uploaded — there is nowhere to upload it to.

Intake

Drop books here

EPUB, MOBI, AZW3, CBZ, or a folder of page images. Drop a folder and its images become one book.

Why it stays here

A book is a personal thing: what you read, when you read it, and who you borrowed it from. There is no upload endpoint on this site, and the page is served with a policy that stops the browser opening a connection to anywhere else even if something tried.

How that is enforced

What it will not do

It does not remove DRM, and it will not pretend a conversion worked when it did not. Protected books are recognised and refused with an explanation. Formats that cannot be produced honestly are not offered.
