Background Remover

Chroma key background removal

This tool treats pixels similar to a "key" color as transparent. It works best on studio shots, green screens, or logos on a flat solid backdrop. For busy natural backgrounds, use dedicated AI matting services instead.

How to use

1. 1Upload an image.
2. 2Use the color picker for the background, or leave default to sample the top-left pixel.
3. 3Raise tolerance until the backdrop disappears; add feather to soften edges.
4. 4Download the transparent PNG.

Key features

Why chroma key?

When backgrounds are uniform, chroma keying is fast, predictable, and does not require multi hundred MB ML downloads in the browser.

Common use cases

• Green screen thumbnails
• Logo knockouts on white
• Product shots on gray seamless

What chroma key removes, and what it does not

• This tool works by colour: you pick a key colour and everything close enough to it becomes transparent. That is reliable on a flat studio background or a green screen, and on product shots taken against plain white or black.
• It is not a subject detection model. On a photograph taken in a room, against a bookshelf or outdoors, there is no single colour to key out and the result will be poor. Those cases need a model based remover, and it is more honest to say so than to let you waste time.
• The upside of the simple approach is that it runs entirely on your machine, instantly, on any size of image, with no upload and no per image credit.

Getting a clean edge

• Start with tolerance low and raise it until the background is gone. Too high and it starts eating the subject, usually beginning with shadows and any part of the subject that shares a tint with the background.
• Feathering softens the boundary by a pixel or two. Without it a keyed edge looks cut out with scissors; with too much the subject looks like it is glowing.
• The single biggest factor is the original photograph. A background lit evenly and separately from the subject keys almost perfectly. One with the subject casting a shadow onto it never fully will, whatever the settings.
