Best Practices for MEF to GBR Conversion

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

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