Troubleshooting ICO to SGI Conversion

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