Open a still shot against a green or blue screen. The screen colour is found from the frame's border, keyed out by chroma with tolerance and softness you set, the green cast is suppressed in the subject, and any ground goes behind.
What this mode does
A screen is one hue lit unevenly, so its pixels scatter in brightness but sit close together in colour. The key measures each pixel's distance from the screen colour in the chroma plane — ignoring brightness — and treats everything near it as ground, with a soft hand-off controlled by the softness slider.
Light bouncing off a green screen tints the subject's edges and hair green. Spill suppression holds the screen's strongest channel down to the level of the other two in the subject's pixels, which removes the cast without turning skin grey.
Steps
- Open the stillThe key colour is read from the border straight away and shown as a chip under Colour key.
- Tune the keyRaise tolerance if screen survives around the edges; lower it if green clothing or eyes are being cut into. Softness widens the hand-off.
- Clean upPaint erase over light stands, tape or the floor beyond the screen; raise spill suppression if hair still looks green.
- Choose the ground and saveAny colour, studio ground, library backdrop or photo, or transparency.
Green or blue screen
Green is the common choice because cameras record green with the least noise, so the key is cleanest. It is the wrong choice when the subject wears green.
A blue screen is better for green clothing and for blonde hair, which picks up less visible spill from blue. The key here works on either: it reads whichever colour dominates the border.
What it cannot do
- Stills only. This page does not key video; a video green screen needs a different engine and is not something it does.
- A wrinkled or badly lit screen has patches far from the key colour; those need the erase brush.
- Green on the subject — a shirt, a plant — is keyed out with the screen. Use a blue screen, or keep it back with the keep brush.
Questions about green screen background
Can I remove a green screen from a video here?
No. This page works on still photographs only, one frame at a time. Video keying is a different job and is not offered.
The edges of the hair are still green. What do I raise?
Spill suppression first; it removes the green cast from the subject's own pixels. If a ring of screen remains outside the hair, raise the tolerance a little or shift the edge in by half a pixel.
It is cutting holes in the subject. Why?
Part of the subject is close to the screen colour — green clothing, or a reflection of the screen on glasses. Lower the tolerance, or paint the area back with the keep brush.
My screen is blue, not green. Does it work?
Yes. The key colour is whatever dominates the frame's border, and you can pick it yourself with 'Pick the screen colour'.
Is the photo uploaded to key it?
No. The key is arithmetic over the photograph's pixels in this tab.

The image you open is read by this page and by nothing else — there is no server behind this domain that could receive it, the outline is worked out inside your own browser either by arithmetic or by an on-device model, and if you ask for a model it is the model that is downloaded to you rather than your photo being sent to it.
