Chroma Key Remover: how to use it
- Drop in a photo on a green screen or another flat, even colour.
- Leave Pick the colour from the corners ticked, or choose the Colour to remove yourself.
- Raise Tolerance until the background disappears, then use Edge softness and Remove colour spill to clean the outline. Download as PNG.
Tips
- Even lighting on the backdrop matters more than the exact colour. Shadows and wrinkles need a higher tolerance.
- Too much tolerance starts eating into the subject. Back off until the edges are solid again.
- For photos without a flat background, use the AI Background Remover.

Chroma Key Remover: what it does and when to use it
Chroma key is the green-screen technique: every pixel close to one chosen colour becomes transparent. Tolerance sets how close counts, Edge softness smooths the border between subject and background, and Remove colour spill takes out the green glow that a green backdrop reflects onto hair and skin.
Because it works by colour alone, it is instant and needs no AI model, and it is exact on graphics with a flat background, such as a logo on white, a product shot on a solid backdrop, or frames from a video filmed against a green screen. Picking the colour from the corners handles most images automatically.
It fails when the subject contains the background colour, such as a green shirt in front of a green screen, or when the backdrop is unevenly lit and full of shadows. For ordinary photos with real backgrounds, the Background Remover uses a segmentation model instead. Download as PNG to keep the transparency.

How do I remove a green screen from a photo?
Pick the green from the background, then raise the tolerance until it disappears and soften the edge. Remove colour spill removes the green tint that reflects onto hair and skin. You get a transparent PNG.
What if my photo was not taken on a green screen?
Use the AI Background Remover, which finds the subject on any background. Chroma key is faster and more exact only when the background is one flat colour.
Can I remove a white background with this?
Yes, for logos and graphics on a plain white background: pick white and set a low tolerance. For photos, the AI Background Remover handles shadows and soft edges better.
