Batch
Convert a shelf at once
Drop in as many books as you like, pick one output format, and convert them together. Each book keeps its own status, so a protected file or a truncated download stops on its own row instead of taking the batch with it.
No upload· Files are read in this tab and never sent anywhere
Intake
Drop your books here
EPUB, MOBI, AZW3, CBZ, PDF, or folders of page images. Every file is identified by its contents, so a book with the wrong extension is still read correctly.
Output format
How a batch behaves
- Files are identified from their bytes, not their extension.
- Each book reports what was carried across and what was not.
- Cancelling a book stops it immediately and frees its memory.
- Downloading everything writes one ZIP with a manifest listing what came from what, including every warning.
If something stops
A book protected by DRM is refused with an explanation rather than a failure. A very large book can exhaust the memory a browser allows one tab — converting it on its own almost always gets through. Everything else is a bug worth knowing about.
