What is CRW?

CRW files are built around lossless compression. Designed for legacy canon dslr photography, raw image processing, they use the image/x-canon-crw MIME type and typically range from varies by content.

What is ARW?

Sony Alpha Raw (ARW) is Sony's proprietary raw image format containing unprocessed sensor data from Sony Alpha and Cyber-shot cameras.

When Should You Use CRW vs ARW?

CRW vs ARW: Key Differences

• •CRW uses lossless compression while ARW uses lossless compression — both take the same approach to file size management.
• •Neither format changes compression philosophy — both are lossless compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
• •Transparency: N/A
• •ARW files tend to be differently sized than CRW
• •Primary audience: CRW is built for legacy canon dslr photography, raw image processing scenarios, while ARW focuses on sony camera post-processing, professional editing — pick the format that matches your output requirement.

Troubleshooting CRW to ARW Conversion

• !ARW shows visible compression artifacts → lower the compression level or switch to a lossless variant
• !The converted ARW image looks washed out → the source CRW likely uses a wider color space than ARW supports
• !ARW file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
• !Text in the converted ARW looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
