Best Practices for JNG to CRW Conversion

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

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