What is PBM?

Portable BitMap (PBM) is a simple monochrome image format that stores each pixel as either black or white in an ASCII text 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 PBM vs BPG?

Use PBM When...

Reach for PBM when your priority is simple image processing, scientific visualization — 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.

PBM vs BPG: Key Differences

  • •The core technical difference: PBM relies on lossless compression whereas BPG uses lossy compression.
  • •Converting from PBM to BPG changes compression type: lossy source becomes smaller but with some quality tradeoff.
  • •Transparency: Supports alpha channel — converting from PBM will merge transparency into a solid background
  • •Storage footprint: Very compact for monochrome images for PBM vs 30-50% smaller than JPEG at same quality for BPG.
  • •Primary audience: PBM is built for simple image processing, scientific visualization scenarios, while BPG focuses on web images with superior compression — pick the format that matches your output requirement.

Advantages of PBM

  • ✓PBM compresses data using lossless methods, keeping file sizes manageable for Simple image processing, scientific visualization.
  • ✓Industry-wide support means PBM files open anywhere — from legacy systems to the latest devices.
  • ✓Lossless quality makes PBM the gold standard for archival and master copies.
  • ✓From professional software to open-source alternatives, PBM works out of the box.

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 PBM 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 PBM 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
