About Image Color Replacer

The Image Color Replacer is a browser-based utility for swapping a specific color in an image with another color. It is handy when you need to change logo or icon colors, adjust skin tones or backgrounds in illustrations, unify brand colors across banner images, or quickly create color variations of a design.

The workflow is straightforward: drop an image, pick the target color using the on-canvas eyedropper or a color picker, choose the replacement color, and apply the change. By adjusting the tolerance slider you can replace not only exact matches but also similar shades, using Euclidean distance in RGB color space for natural results. The edge smoothing feature blends color boundaries for seamless transitions.

Unlimited undo/redo (Ctrl+Z / Ctrl+Y) lets you experiment freely and achieve the perfect color. Everything runs locally in the browser via the Canvas API, so no data ever leaves your machine — safe even for confidential images.

Drop or select an image file and check the preview.
Click on the canvas to pick the target color with the eyedropper, or set it directly with the color picker, then choose the replacement color and adjust the tolerance.
