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.

What is BPG?

Better Portable Graphics (BPG) is a modern image format based on HEVC video compression, offering excellent compression efficiency.

When Should You Use ARW vs BPG?

Use ARW When...

Reach for ARW when your priority is sony camera post-processing, professional editing — its uncompromising quality ensures every detail is preserved.

Use BPG When...

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

ARW vs BPG: Key Differences

  • •ARW and BPG diverge on compression: lossless compression for the source, lossy compression for the target.
  • •Moving from ARW (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.
  • •Storage footprint: 20-40MB per photo for ARW vs 30-50% smaller than JPEG at same quality for BPG.
  • •Use case fit: ARW targets sony camera post-processing, professional editing and BPG targets web images with superior compression — your choice depends on which workflow stage you are serving.

Advantages of ARW

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

Advantages of BPG

  • ✓BPG applies lossy compression specifically calibrated for Web images with superior compression.
  • ✓BPG enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓BPG delivers impressive compression ratios, shrinking files dramatically while keeping visual quality high.
  • ✓You will find BPG support built into virtually every tool that handles Web images with superior compression — no plugins or converters needed.

Best Practices for ARW to BPG Conversion

  • →Before converting ARW to BPG, decide whether you need maximum quality or smallest file size — this determines which format truly fits
  • →Save a master copy in a lossless format before converting to BPG — you cannot recover detail lost during lossy compression
  • →Check the color profile: ARW images may use a wider gamut than BPG supports, causing a visible shift after conversion
  • →Resize images to the final display dimensions before converting — this avoids unnecessary processing of oversized files
  • →Run a single test conversion first to verify quality meets your standards
  • →Strip unnecessary metadata to reduce file size after conversion

Troubleshooting ARW to BPG Conversion

  • !Converting ARW to BPG gives blurry output → increase the quality setting before conversion
  • !Colors look different in BPG than ARW → check color profile mismatch (sRGB vs Adobe RGB)
  • !File size changed more than expected → BPG uses different compression, file size differences of 2-5x are normal
  • !Transparent areas in ARW turned white in BPG → BPG may not support transparency
