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.
EMF at a glance
EMF
Convert to EMF when placing vector graphics into Windows-centric documents, presentations, reporting systems, or print workflows that expect an Office-friendly scalable graphic.
It is suitable for charts, diagrams, and embedded illustrations in desktop-office environments.
For cross-platform web and design exchange, SVG or PDF are often better choices.
