CR2 at a glance
CR2
Convert to CR2 when preserving Canon originals or maintaining a workflow that expects Canon raw files.
It is useful for archive retention, raw editing, and non-destructive photo finishing.
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.
