PEF vs PNG: Key Differences

  • •PEF and PNG diverge on compression: lossless compression for the source, lossless compression for the target.
  • •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •Transparency: Full alpha channel transparency, supports semi-transparent pixels
  • •File sizes: PEF files typically range 15-45MB per photo and PNG files 20KB to several MB.
  • •Use case fit: PEF targets pentax camera post-processing and PNG targets graphics, logos, images requiring transparency — 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 PNG

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

Troubleshooting PEF to PNG Conversion

  • !PNG shows visible compression artifacts → lower the compression level or switch to a lossless variant
  • !The converted PNG image looks washed out → the source PEF likely uses a wider color space than PNG supports
  • !PNG file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
  • !Text in the converted PNG looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
