Steps

Upload an image.
Select the source color (or click the image to pick it).
Choose the target color.
Adjust tolerance and click Apply.
Confirm the preview and download as PNG.

Your image never leaves your device.

Best practices

For photos with gradients, keep tolerance lower to avoid color bleeding.
For flat icons or logos, slightly higher tolerance gives better coverage.
Large images are auto-downscaled for preview (download matches).

Transparency note

Alpha channels are preserved, so transparent backgrounds stay transparent.
