Why convert books locally
Book-length uploads are slow and put your library on someone else’s server. Local conversion is faster than a round-trip upload for large files and keeps the collection yours.
The full book pipeline, all on-device
A scanned book usually wants three steps: convert the DjVu to PDF, OCR it so you can search and quote it, and compress it so it fits on an e-reader or in an email. Every step runs in your browser here, so a rare or personal book never has to touch a server.
