What is a Replace Color in Image tool?

A Replace Color in Image tool lets you select a specific color in a photo and swap it for a different color. This tool runs entirely in your browser using the HTML canvas API, so your image never leaves your device.

How do I replace a background color?

Upload your image, click the eyedropper, and tap the background. Raise the tolerance slider until the whole background is highlighted in the preview, then pick a new background color.

What does tolerance mean?

Tolerance controls how far a pixel can be from your selected color and still be replaced. A low tolerance replaces only pixels that are almost exactly the same. A high tolerance replaces many similar shades.

Can I replace multiple colors at once?

This tool replaces one color per session. For multi-color replacement, save the result and open the tool again to replace another color.

What image formats are supported?

The tool accepts JPG, JPEG, PNG, WebP, GIF, and BMP images. Output is always PNG so transparency and quality are preserved.

Will the replacement look natural?

For flat backgrounds and simple logos, the result looks clean. For photos with soft gradients and shadows, use the softness slider and a moderate tolerance to blend the new color naturally.

Does the tool upload my image?

No. All pixel processing happens in your browser. The image file is never sent to a server.

Can I replace the color of clothing in a photo?

Yes, as long as the clothing color is distinct enough from skin and background. Use a low tolerance first, then increase it carefully, and use softness to keep edges natural.

Is there a file size limit?

The practical limit depends on your device memory. Most phones handle images up to 20 megapixels comfortably.

Can I use this on a phone?

Yes. The tool works in any modern mobile browser, including Safari on iPhone and Chrome on Android.

Can I undo a replacement?

Yes. Reset restores the original image at any time. Changes are applied live to the preview, so nothing is permanent until you download.

Yes. The Replace Color in Image tool is free, needs no signup, and adds no watermarks.
