EPUB in sintesi
EPUB
Convert to EPUB when you need a flexible, reflowable ebook for wide distribution, library use, independent publishing, or archival storage of structured long-form text.
It is the right target for novels, manuals, educational content, and narrative works intended for multiple reading apps and devices.
Choose EPUB when portability and reader adaptability matter more than exact fixed-page layout.
3GP in sintesi
3GP
Convert to 3GP when preserving or processing older mobile phone footage, MMS-era videos, or device-targeted clips for constrained mobile environments.
It is a reasonable compatibility target for archival workflows involving legacy handsets.
For general-purpose delivery, MP4 is the more practical modern choice.
