Remove a brown background
Free, no signup, and your image never leaves your device.
Pick the brown with the eyedropper and it is keyed out everywhere it appears. The numbers below are the ones this tool actually uses, so you can set it up in one go.

|---|---|
| RGB | 139, 90, 43 |

| Relative luminance | 13% |
| Match radius at the suggested tolerance | ΔE 6.1 |
Why this tolerance
A muted colour is close enough to browns and skin tones to need care, but far enough from neutral greys to take a moderate tolerance. The suggested value is a middle setting.

When this works well
A flat or near-flat brown area that is clearly different from your subject. Compression noise and lighting variation are expected — that is what the tolerance absorbs. Where it struggles is a subject containing the same brown, and there the brush is faster than any amount of slider tuning.
Common questions
What tolerance should I use for a brown background?
Start at 32 and adjust from there. Raise it if flecks of brown survive; lower it if the subject starts disappearing.
It removed part of my subject as well. What now?
The subject contains something close to that brown. Lower the tolerance until the subject is safe, accept the leftover specks, and remove those with the brush — that is reliably faster than finding a tolerance that does both.
Does it remove brown inside the subject too?
Only if you want it to. Leave connectivity on and only the area joined to the edges goes; turn it off and every matching pixel goes, including enclosed gaps.
