Troubleshooting PSD to CPT Conversion

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