Frequently asked questions
Is converting AZW3 to MOBI free?
Yes. Conversion is free, with no sign-up and no watermarks.
Is my AZW3 file uploaded to a server?
Yes. Unlike most conversions on this site, AZW3 to MOBI 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 AZW3 to MOBI?
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.
