Troubleshooting PEF to PSD Conversion

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