Knock a color out of a WebP
Turning a solid background into transparency is one of the most common image chores — freeing a logo from its white box, dropping a product onto a colored page, or preparing a graphic to sit over anything. This tool removes a color you choose from a WebP and replaces it with real transparency, then saves a WebP that keeps its alpha channel.
Drop a WebP, click or pick the background color to remove, and adjust the tolerance until the edges look clean in the preview. When it is right, download a transparent WebP ready to layer over any color or image. It works best on flat, uniform backgrounds rather than busy scenes.

When to use color knockout
Free a logo or icon
Strip the white box from a flat logo so it drops cleanly onto any colored header, slide or page.
Prep product cut-outs
Remove a plain studio backdrop from a product shot to place it over your own background.
True WebP transparency
The result is saved with a genuine alpha channel, so the transparency travels with the file everywhere WebP is supported.
Frequently Asked Questions
How does making a WebP transparent work?
You pick a color — usually a flat background like white — and the tool turns every pixel close to that color into transparency. A tolerance control decides how similar a pixel has to be to be removed.
Does this work like an AI background remover?
No. It removes a color you choose, which is perfect for flat, uniform backgrounds such as a solid white or green backdrop. It is not designed to cut a subject out of a busy, detailed background.
What is the tolerance setting for?
Tolerance widens or narrows the range of shades treated as the background. Raise it if edges of the color remain; lower it if parts of your subject are disappearing.
Is transparency saved in the WebP?
Yes. WebP supports a full alpha channel, so the knocked-out areas are saved as genuine transparency you can place over any background.
Are my images uploaded?
No. The color is removed in your browser with the canvas, so your image never leaves your device.
