APNG vs HDR: Key Differences

  • •APNG and HDR diverge on compression: lossless compression for the source, lossless compression for the target.
  • •Since both APNG and HDR use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
  • •Alpha channel support: HDR lacks transparency support.
  • •File sizes: APNG files typically range Larger than GIF but better quality and HDR files 5-30MB for typical HDR maps.
  • •Use case fit: APNG targets web animations, game sprites, animated icons and HDR targets hdri lighting, panoramic photography — your choice depends on which workflow stage you are serving.

Troubleshooting APNG to HDR Conversion

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