When Should You Use RW2 vs 3FR?

RW2 vs 3FR: Key Differences

• •RW2 uses lossless compression while 3FR uses lossless compression — both take the same approach to file size management.
• •Since both RW2 and 3FR use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •Alpha channel support: 3FR lacks transparency support.
• •RW2 files are typically 20-45MB per photo while 3FR files range 40-80MB per image from medium-format sensors
• •Use case fit: RW2 targets panasonic/lumix camera raw editing and 3FR targets medium-format photography, professional studio — your choice depends on which workflow stage you are serving.

Advantages of RW2

• ✓RW2 uses lossless compression tailored for Panasonic/Lumix camera raw editing.
• ✓RW2 is supported natively on virtually every device, browser, and operating system.
• ✓RW2 files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓RW2 integrates seamlessly with all major creative tools and workflows.

Advantages of 3FR

• ✓At its core, 3FR relies on lossless encoding — a design choice that makes it perfect for Medium-format photography, professional studio.
• ✓You won't run into compatibility issues with 3FR — it's a universal standard across platforms.
• ✓File size management with 3FR: larger files guaranteed to match the original exactly.
• ✓Every major application in the Medium-format photography, professional studio space supports 3FR natively.

Troubleshooting RW2 to 3FR Conversion

• !3FR shows visible compression artifacts → lower the compression level or switch to a lossless variant
• !The converted 3FR image looks washed out → the source RW2 likely uses a wider color space than 3FR supports
• !3FR file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
• !Text in the converted 3FR looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
