Use BPG When...

Reach for BPG when your priority is web images with superior compression — its efficient compression makes sharing fast and storage minimal.

RW2 vs BPG: Key Differences

  • •RW2 and BPG diverge on compression: lossless compression for the source, lossy compression for the target.
  • •Moving from RW2 (lossy) to BPG (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
  • •How transparency is handled: BPG does not support alpha channels — transparent areas in the source will become opaque.
  • •RW2 files are typically 20-45MB per photo while BPG files range 30-50% smaller than JPEG at same quality
  • •Primary audience: RW2 is built for panasonic/lumix camera raw editing scenarios, while BPG focuses on web images with superior compression — pick the format that matches your output requirement.

Advantages of RW2

  • ✓RW2 applies lossless compression specifically calibrated for Panasonic/Lumix camera raw editing.
  • ✓RW2 enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓RW2 guarantees every bit of the original data survives — no approximations, no shortcuts.
  • ✓You will find RW2 support built into virtually every tool that handles Panasonic/Lumix camera raw editing — no plugins or converters needed.

Advantages of BPG

  • ✓The lossy nature of BPG means file sizes stay reasonable while handling Web images with superior compression efficiently.
  • ✓From mobile devices to enterprise servers, BPG is recognized and supported everywhere.
  • ✓Storage and bandwidth costs drop significantly when using BPG thanks to its efficient compression.
  • ✓BPG is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Troubleshooting RW2 to BPG Conversion

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