What is HEIF?

HEIF (High Efficiency Image File Format) is a modern container format that stores images encoded with the HEVC (H.265) codec. It delivers significantly smaller file sizes than JPEG while maintaining superior image quality.

What is CRW?

Canon Raw CRW — stored as image/x-canon-crw — uses lossless encoding to handle legacy canon dslr photography, raw image processing. Typical file sizes: varies by content.

When Should You Use HEIF vs CRW?

Use HEIF When...

Reach for HEIF when your priority is modern photography, ios/macos workflows, efficient storage and sharing — its efficient compression makes sharing fast and storage minimal.

Use CRW When...

Reach for CRW when your priority is legacy canon dslr photography, raw image processing — its uncompromising quality ensures every detail is preserved.

HEIF vs CRW: Key Differences

  • •The core technical difference: HEIF relies on lossy compression whereas CRW uses lossless compression.
  • •Moving from HEIF (lossless) to CRW (lossless) means the output file will be larger — but every bit of the original is preserved.
  • •How transparency is handled: CRW supports transparency, so alpha information is preserved during conversion.
  • •CRW files tend to be differently sized than HEIF
  • •HEIF is optimized for modern photography, ios/macos workflows, efficient storage and sharing while CRW is designed for legacy canon dslr photography, raw image processing — choose based on your specific workflow needs

Troubleshooting HEIF to CRW Conversion

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