Best Results Tips

  • • Choose images with white or light backgrounds
  • • Higher contrast between subject and background works better
  • • Avoid subjects with large white areas
  • • PNG format recommended for best quality
Precise: Tolerance 5, suitable for pure white backgrounds
Standard: Tolerance 10, suitable for most cases
Loose: Tolerance 25, suitable for backgrounds with slight color variations
0 (Precise)50 (Balanced)100 (Loose)

Lower tolerance removes only pixels closer to the key color; higher tolerance removes a broader range.

If set, removal targets this color ± tolerance. Leave empty for auto-detect.
