Frequently asked questions
Is converting EPUB to AZW3 free?
Yes. Conversion is free, with no sign-up and no watermarks.
Is my EPUB file uploaded to a server?
Yes. Unlike most conversions on this site, EPUB to AZW3 runs on our server: the file is sent over an encrypted connection, converted in an isolated environment without network access and deleted right after you download the result, or within 3 hours at the latest.
What carries over from EPUB to AZW3?
Text, chapters and the table of contents, the cover, pictures, bold and italics. The text reflows to fit the reader’s screen, so pages break differently. Books with copy protection (DRM), like most store-bought ones, can’t be converted. DjVu pages are pictures: they go into PDF as they are, and TXT needs a text layer.
