What is PPM?

Portable PixMap (PPM) is a simple color image format that stores RGB pixel data in ASCII or binary representation.

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 PPM vs BPG?

Use PPM When...

Reach for PPM when your priority is simple color image processing, academic use — 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.

PPM vs BPG: Key Differences

  • •PPM and BPG diverge on compression: lossless compression for the source, lossy compression for the target.
  • •Moving from PPM (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.
  • •PPM files are typically Larger than JPEG, smaller than BMP for same data while BPG files range 30-50% smaller than JPEG at same quality
  • •Use case fit: PPM targets simple color image processing, academic use and BPG targets web images with superior compression — your choice depends on which workflow stage you are serving.

Advantages of PPM

  • ✓PPM applies lossless compression specifically calibrated for Simple color image processing, academic use.
  • ✓PPM enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓PPM guarantees every bit of the original data survives — no approximations, no shortcuts.
  • ✓You will find PPM support built into virtually every tool that handles Simple color image processing, academic use — no plugins or converters needed.

Advantages of BPG

  • ✓BPG uses lossy compression tailored for Web images with superior compression.
  • ✓BPG is supported natively on virtually every device, browser, and operating system.
  • ✓BPG files are compact and quick to transfer, even over slow connections.
  • ✓BPG integrates seamlessly with all major creative tools and workflows.

Troubleshooting PPM 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 PPM 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
