Best Practices for GBR to JXL Conversion

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

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