When Should You Use PEF vs BPG?

Use PEF When...

Reach for PEF when your priority is pentax camera post-processing — 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.

PEF vs BPG: Key Differences

  • •PEF and BPG diverge on compression: lossless compression for the source, lossy compression for the target.
  • •Converting from PEF to BPG changes compression type: lossy source becomes smaller but with some quality tradeoff.
  • •How transparency is handled: BPG does not support alpha channels — transparent areas in the source will become opaque.
  • •Storage footprint: 15-45MB per photo for PEF vs 30-50% smaller than JPEG at same quality for BPG.
  • •Use case fit: PEF targets pentax camera post-processing and BPG targets web images with superior compression — your choice depends on which workflow stage you are serving.

Advantages of PEF

  • ✓PEF uses lossless compression tailored for Pentax camera post-processing.
  • ✓PEF is supported natively on virtually every device, browser, and operating system.
  • ✓PEF files are bit-for-bit perfect, preserving every pixel and sample for professional work.
  • ✓PEF integrates seamlessly with all major creative tools and workflows.

Advantages of BPG

  • ✓BPG compresses data using lossy methods, keeping file sizes manageable for Web images with superior compression.
  • ✓Industry-wide support means BPG files open anywhere — from legacy systems to the latest devices.
  • ✓Small file sizes make BPG ideal for email, web uploads, and cloud storage.
  • ✓From professional software to open-source alternatives, BPG works out of the box.

Troubleshooting PEF 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 PEF 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
