What is APNG?

Animated PNG (APNG) extends the PNG format with frame-based animation support while maintaining full backward compatibility with standard PNG decoders.

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 APNG vs BPG?

Use APNG When...

Reach for APNG when your priority is web animations, game sprites, animated icons — 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.

APNG vs BPG: Key Differences

  • •APNG and BPG diverge on compression: lossless compression for the source, lossy compression for the target.
  • •Converting from APNG to BPG changes compression type: lossy source becomes smaller but with some quality tradeoff.
  • •Transparency: Supports alpha channel — converting from APNG will merge transparency into a solid background
  • •Storage footprint: Larger than GIF but better quality for APNG vs 30-50% smaller than JPEG at same quality for BPG.
  • •Primary audience: APNG is built for web animations, game sprites, animated icons scenarios, while BPG focuses on web images with superior compression — pick the format that matches your output requirement.

Advantages of APNG

  • ✓At its core, APNG relies on lossless encoding — a design choice that makes it perfect for Web animations, game sprites, animated icons.
  • ✓You won't run into compatibility issues with APNG — it's a universal standard across platforms.
  • ✓File size management with APNG: larger files guaranteed to match the original exactly.
  • ✓Every major application in the Web animations, game sprites, animated icons space supports APNG natively.

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 APNG to BPG Conversion

  • !Converting APNG to BPG gives blurry output → increase the quality setting before conversion
  • !Colors look different in BPG than APNG → 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 APNG turned white in BPG → BPG may not support transparency
