ARI at a glance
ARI
Digital photography fragmented into many manufacturer-specific raw formats because camera makers optimized for their own sensors, metadata, and software ecosystems rather than for one shared public raw standard.
CRW at a glance
CRW
Early Canon digital-camera workflows used raw formats like CRW before the later EOS raw families stabilized around CR2 and then CR3.

FAQs
Why convert ARI to CRW?
Choose CRW as target when maintaining compatibility with older Canon raw libraries or recovering historical camera originals.
What changes when converting ARI to CRW?
Convert to CRW when maintaining compatibility with older Canon raw libraries or recovering historical camera originals. In most current workflows it is a source to preserve or migrate, not a preferred new output format.
What should I review after converting ARI to CRW?
After conversion, review these destination checks: Open converted output in vendor photo software and verify behavior on real samples; Compare output against the expected raw quality profile; Compatibility often depends on vendor or decoder support.
How can I keep quality stable in ARI to CRW conversion?
Run representative samples, keep settings deterministic, and monitor these risks: They are source formats, not publication-ready outputs; Compatibility often depends on vendor or decoder support; Validate destination compatibility before large-batch conversion.
