CRW is Canon's original RAW format, based on the Camera Image File Format (CIFF) and used by earlier Canon digital cameras before being superseded by CR2. When archiving or restoring older Canon photos, PNG is often the better target than JPG, since it's lossless and won't introduce further compression artifacts on top of files that may already be decades old.
Converting CRW to PNG demosaics the sensor data and writes a lossless file, making it the practical choice for preserving maximum quality when revisiting an older Canon photo archive.

Why choose PNG instead of JPG for old CRW files?
PNG is lossless, which avoids stacking further compression loss on top of older photo files when archiving them in a modern format.
Which cameras produce CRW files?
CRW was Canon's original RAW format, used by earlier Canon digital cameras before being replaced by the CR2 format.
Can I convert an entire archive of CRW files at once?
Yes, Batch Mode processes an entire folder of CRW files in one pass, including nested sub-folders if recursive scanning is enabled.
