Troubleshooting JNG to 3FR Conversion

  • !3FR shows visible compression artifacts → lower the compression level or switch to a lossless variant
  • !The converted 3FR image looks washed out → the source JNG likely uses a wider color space than 3FR supports
  • !3FR file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
  • !Text in the converted 3FR looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
