Troubleshooting JPG to X3F Conversion

  • !X3F shows visible compression artifacts → lower the compression level or switch to a lossless variant
  • !The converted X3F image looks washed out → the source JPG likely uses a wider color space than X3F supports
  • !X3F file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
  • !Text in the converted X3F looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
