Replace a color in a JPG.

Drop the JPG, click the from color to pick what should change, click to for its replacement, and set the tolerance to decide how close a pixel must be to match.

Yes. From white, #ffffff, to your color, with a tolerance of 5 to 15 percent for off-whites. Any other white object in the photo changes too.

Yes. Pick the source color and set to white. It is a quick way to blank a colored background or make a clean, minimal version of a graphic.

Lower the tolerance. And check whether the color appears elsewhere: the tool replaces every matching pixel, not an area.

JPEG cannot hold transparency and loses a little detail every time it is saved, so the result is written as a lossless PNG. It is larger than the JPG it came from; run it through the PNG compressor, or convert it back to JPG, once the editing is done.

No. The PNG is a new file written from the pixels and carries no EXIF. Keep the original JPG beside the edited PNG if the camera data matters.

One at a time. Replace the first, download, drop the result and replace the next. Each pass builds on the last.

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.

No. The file is decoded, drawn and re-encoded by your browser's canvas, and the page makes no request with it. You can load the page, go offline and keep working; nothing is stored either.

No. The "Replace a color in a JPG" tool is free and opens without a sign-in, an account or an install.

Up to 100 MB per file, the limit the tool states under its drop area. A larger file is refused with a plain message instead of being decoded.

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 result has the same width and height in pixels as the source.
