Online Image Color Invert Tool

Each RGB channel becomes 255 minus its source value: RGB(10,120,250) becomes RGB(245,135,5). Alpha and image dimensions are unchanged. This is channel inversion, not an HSL hue rotation.

PNG compression is lossless. Two inversions restore opaque RGB values mathematically, but browser colour conversion and transparent-pixel rounding may affect a file round trip; keep the original.

One image at a time, up to 25 MiB and 24 million pixels. There is no strength control or region selection. Export is a static PNG; animation, layers and original metadata are not preserved.
