PEF vs FFF: Key Differences

•PEF and FFF 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.
•Alpha channel support: FFF handles transparency.
•FFF files tend to be differently sized than PEF
•PEF is optimized for pentax camera post-processing while FFF is designed for medium format photography, hasselblad post-processing — choose based on your specific workflow needs

Best Practices for PEF to FFF Conversion

→Before converting PEF to FFF, decide whether you need maximum quality or smallest file size — this determines which format truly fits
→Save a master copy in a lossless format before converting to FFF — you cannot recover detail lost during lossy compression
→Check the color profile: PEF images may use a wider gamut than FFF supports, causing a visible shift after conversion
→Resize images to the final display dimensions before converting — this avoids unnecessary processing of oversized files
→Run a single test conversion first to verify quality meets your standards
→Strip unnecessary metadata to reduce file size after conversion

Troubleshooting PEF to FFF Conversion

!Converting PEF to FFF gives blurry output → increase the quality setting before conversion
!Colors look different in FFF than PEF → check color profile mismatch (sRGB vs Adobe RGB)
!File size changed more than expected → FFF uses different compression, file size differences of 2-5x are normal
!Transparent areas in PEF turned white in FFF → FFF may not support transparency
