JPG color swap.

Drop the JPG, click the color to swap or type its hex code, pick the new color, download. It takes seconds.

Yes. Red as the from color, blue as the to color, with Preserve shades on so the reds keep their lighting instead of all becoming one flat blue.

A hue shift moves every color at once. A swap targets one color and leaves the rest untouched.

Yes, with Preserve shades on: the lightness gradient stays and only the hue changes, so the transition remains smooth.

One image at a time. Each swap runs on your device in a moment, so a series goes quickly: drop, swap, download, next.

Click the color in the photo you want gone, or type its hex code, then choose the color that should take its place. Tolerance sets how far a pixel may stray from the first color and still be replaced; photos need more of it than flat graphics, usually 15 to 30 percent.

The edit is written as a PNG because PNG stores every pixel exactly, with a full alpha channel, so the result can be edited again without a second round of loss.

No. The browser decodes the image and the tool writes a new file from its pixels, so camera EXIF, GPS position and text chunks in the original are not copied into the result. Keep the original file if you need them.
