JBIG in sintesi
JBIG
Convert to JBIG when compressing monochrome scanned documents, line art, or text-heavy page imagery where bi-level efficiency matters.
It is useful for document-imaging pipelines rather than everyday photo delivery.
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.
