When Should You Use RAW vs ARW?

RAW vs ARW: Key Differences

• •RAW and ARW diverge on compression: lossless compression for the source, lossless compression for the target.
• •Since both RAW and ARW use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •How transparency is handled: ARW supports transparency, so alpha information is preserved during conversion.
• •Storage footprint: 20-50MB per photo depending on camera for RAW vs 20-40MB per photo for ARW.
• •RAW is optimized for professional photography, post-processing, editing while ARW is designed for sony camera post-processing, professional editing — choose based on your specific workflow needs

Troubleshooting RAW 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 RAW 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
