Troubleshooting QOI to XWD Conversion

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