JBIG at a glance
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.
AMR at a glance
AMR
Convert to AMR when the target is a speech-oriented mobile or telephony workflow, such as voicemail systems, call recordings, or compatibility with older handset ecosystems.
It is useful when bandwidth and voice intelligibility matter more than music quality.
For music or general listening, AAC, Opus, or WAV are better targets.
