How colour-based transparency works
Colour matching, not object detection
This tool finds every pixel close to the colour you pick and sets its alpha to zero. It does not know what a subject is, which makes it fast and exact on flat backgrounds and unsuitable for a photograph where the background varies.
What tolerance controls
Matching is done in Lab colour space, which measures difference the way the eye does rather than by raw RGB distance. Tolerance sets how far from your chosen colour a pixel can be and still be removed. Low values take only the exact colour; higher values sweep up the anti-aliased pixels around edges.
When to reach for the AI remover instead
If your background has gradients, texture, shadows or a photographed scene, colour matching will either leave halos or eat into the subject. Those cases need the AI background remover, which separates subject from background by understanding the image.
Getting clean edges
A JPG background is never one flat colour, because compression spreads it into a range of near-identical values. That is why a white background can need a tolerance of 20 or more before the last grey pixels disappear. Raise it until the fringe goes, then stop.
The output must be PNG
Transparency needs an alpha channel and JPG does not have one. The result is always a PNG so the transparency survives; saving it as JPG afterwards would fill it back in with white.
How to make an image transparent
Upload your image
Drop in a PNG, JPG, WebP, or SVG, or click to browse. Images with a flat background work best.
Pick the colour to remove
Choose the background colour, then raise tolerance until the fringe around your subject disappears. The checkerboard shows exactly what has been knocked out.

Where knocking out a colour helps
Product photos
Strip a plain studio backdrop so products sit on any page background.
Logos from documents
Recover a usable transparent logo from a PDF export or screenshot with a white background.
Green screen stills
Knock out a chroma key backdrop from a frame grab or photograph.
Stickers and overlays
Cut a flat-background graphic free so it can be layered anywhere.
Or just ask
Describe the edit in your own words
Type what you want changed and the assistant does it on the canvas — each step lands as a layer you can reopen, so nothing it does is baked in.
