Best Practices for PEF to CR3 Conversion

→Before converting PEF to CR3, 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 CR3 — you cannot recover detail lost during lossy compression
→Check the color profile: PEF images may use a wider gamut than CR3 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 CR3 Conversion

!Converting PEF to CR3 gives blurry output → increase the quality setting before conversion
!Colors look different in CR3 than PEF → check color profile mismatch (sRGB vs Adobe RGB)
!File size changed more than expected → CR3 uses different compression, file size differences of 2-5x are normal
!Transparent areas in PEF turned white in CR3 → CR3 may not support transparency
