Quality Setting

The quality slider affects several aspects of icon generation:

• Image Compression: Higher quality uses less compression for better details
• Anti-aliasing: Higher quality applies better edge smoothing
• Dithering: Higher quality uses more sophisticated color blending techniques
• Detail Preservation: Higher quality retains more fine details when scaling

Different quality levels are recommended for different uses:

• High Quality (90-100%): Best for application icons, desktop icons, and professional use
• Medium Quality (75-89%): Good for website icons and general purpose use
• Low Quality (60-74%): Suitable for small UI elements and when file size matters most
