Removal Mode

Key Colors

Every key color gets removed — add the background AND things like glows or shadows. Click a chip to delete it. Eyedropper stays on for multiple picks (Esc to stop).

Edge Refinement

Shrink edge0

Feathering3

Edge threshold25

Shrink edge cuts N pixels off the whole outline — removes glow/halo fringes of any color without touching the interior. Negative values grow the edge instead.

Matte Cleanup

Protect interior (erase from edges only)

Keep main subjects only

Solidify0

Clean specks15

Fill holes15

Protect interior: only erases areas reachable from the image border — key colors can no longer punch holes inside the subject (disable it if your subject has real see-through gaps). Keep main subjects: drops everything much smaller than the biggest kept piece(s). Solidify: pushes semi-transparent areas to fully opaque/transparent (fixes AI gray blotches). Specks/Holes: remove leftover islands / fill wrongly-erased gaps. 0 = off.
