Troubleshooting HEIFS to JNG Conversion

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