How to use, limits & privacy

Choose a JPEG, PNG or WebP image and select source and replacement colors. A pixel matches when every RGB channel differs by at most the tolerance. Every matching visible pixel is replaced, including matching subject pixels; alpha remains unchanged. This is color replacement, not automatic background removal or subject detection. Export is a still PNG using the first decoded frame. Browser color management and image orientation apply. No metadata preservation is promised.

Images: JPEG/PNG/WebP, 8 MiB, 12 megapixels. Dimensions are checked before decoding; JPEG frame dimensions must occur within the first 256 KiB. Corrupt or unsupported inputs are rejected.

Inputs are never uploaded. Results are rendered as text or a locally generated image. Original files remain unchanged. Changing input invalidates previous results.
