Tolerance includes nearby shades instead of replacing only one exact RGB value.

Choosing an effective tolerance

Start with a low tolerance for flat graphics and increase it gradually for anti-aliased edges or photographed objects. A high tolerance can affect unrelated colors, so review the full preview before export. This method changes RGB values and preserves each pixel alpha value.

คำถามที่พบบ่อย

What does tolerance control?

Tolerance sets how far a pixel color may be from the selected source color and still be replaced.

Does it preserve transparency?

Yes. The replacement changes RGB values while leaving alpha values unchanged.
