Frequently asked questions

Is converting EPUB to PDB free?

Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.

Are my EPUB files uploaded anywhere?

This conversion runs on our server, because reading an EPUB file needs calibre, which does not run in a browser. Your file is sent over an encrypted connection, and both it and the result are deleted 72 hours after the conversion. The server has no internet access while it works on your file.

How large can the EPUB file be?

Up to 1 GB per file. This conversion runs on our server, which accepts files up to that size.

Will the PDB look the same as the EPUB?

The text, chapters and pictures are kept. The look can differ: PDB readers use their own fonts and page sizes, so page breaks move.

Can I convert several EPUB files at once?

Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
