About replacing a colour here

Every pixel close enough to the colour you clicked is swapped, wherever it is in the image. That makes it good for recolouring a logo, changing a flat background or fixing one wrong brand colour.

Tolerance decides how close is close enough. Photos need a higher tolerance than flat graphics, since a real surface is never one exact colour.

Common questions

Is the replace colour tool free?

Yes, properly free. No paid tier, no trial, no watermark on the result and nothing to sign up for. Put as many files through it as you like, as often as you like.

Are my files uploaded to a server?

No. The replace colour tool runs inside your browser, on your own machine, so your files never go anywhere. Big ones are fine too, up to whatever your browser can hold.

How do I change the colour of something in a photo?

Click the colour you want to change, pick the new one, and every pixel close enough to the original is swapped. It works beautifully on flat colour, so logos, icons, diagrams and graphics with clean areas are the ideal case. A photograph of a shirt has hundreds of shades in it, so expect to raise the tolerance and still touch up the edges.

Why did other parts of the picture change too?

The tolerance is set high enough to include colours you didn't intend. Every pixel within that distance of the one you clicked is changed, wherever it happens to be in the image, so a sky and a pair of blue jeans can easily fall into the same range. Lower the tolerance until only the area you want is affected.
