Photo color changer.

Drop a photo of the room, pick the current wall color, choose the new one. Walls carry shadows and lighting gradients, so use a higher tolerance, 20 to 35 percent, to cover the whole surface.

Yes, and it is a good use: photograph the room, try the colors you are considering, save each version and compare before buying paint.

Pick the petals' color and the new one. Petals are gradients, so keep Preserve shades on to keep their natural variation.

Not directly. This tool replaces colors; it does not remove them. A selective-color effect would mean replacing every other color with gray, which is slow. An editor with masks does it better.

Very, for distinct colors. Subtle gradients need a higher tolerance; the mask preview shows which pixels will change before you commit.

The original file is never touched. To start over, drop it again. Save each version you like before the next change.

No app needed: it works in any mobile browser. Pick a photo, change the color, save the result.

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 Photo color changer is free and opens without a sign-in, an account or an install.

Nothing. The Photo color changer holds your input in the page's memory, so closing or reloading the tab clears it, and it saves nothing in this browser.

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.

No, it takes one file at a time. If you drop or choose several, only the first is used; run the tool again for the next one.

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.

No. The result has the same width and height in pixels as the source.
