ASF at a glance
ASF
Convert to ASF when you need compatibility with older Windows Media infrastructures, enterprise archives, or inherited streaming libraries that still rely on Microsoft's classic container family.
It is useful for preservation and controlled legacy playback.
For current browser and consumer delivery, MP4 or WebM are generally better choices.
DJVU at a glance
DJVU
Convert to DjVu when the source is a scanned document set and the goal is a compact, page-faithful file for archival reading or repository distribution.
It is a good target for books, historical periodicals, manuals, and other materials that are fundamentally page images rather than editable text documents.
If broad end-user compatibility is the priority, PDF is usually the easier delivery format.
