About this conversion

What happens

The EPUB package converts offline and independent KF8 structure checks gate the download.

Limits

100 MiB input. 400 MiB expanded content and 200 MiB output.

Things to know

AZW3 retains more modern styling than legacy MOBI, but reader rendering can still differ. DRM, encryption, active XML entities, malformed packages, and resource-limit violations fail closed.
