Converter questions
Is the converter really free?
Yes. Every pair is free, with no signup, no email step and no watermark, up to 5 conversions a day.
What happens to my file?
It is converted on our server and deleted the moment your download starts. Nothing is stored, indexed or shared.
How large can a file be?
Up to 30 MB, which covers almost every text-based book. Heavily illustrated art books are the usual exception.
Can I convert a scanned PDF?
A scan has no text layer to extract, so the result is an EPUB of images rather than words you can resize or search.
Does it work on a phone?
Yes. Pick the file from your phone, convert, and open the result straight in the Celer app to keep reading.
