Inverting an image flips every colour to its opposite: each red, green and blue value becomes 255 minus itself, so black turns white, white turns black, and every hue becomes its complement. The result looks like an old photographic negative. This tool applies the inversion per pixel across the whole image.
Colour inversion is handy for turning a scanned film negative into a positive preview, for creating a striking negative effect, for checking how artwork reads in a dark-on-light versus light-on-dark layout, or simply as a quick creative filter. The output keeps your original format and dimensions - a PNG stays a PNG (transparency preserved), a JPEG stays a JPEG.
Everything runs entirely locally in your browser on a canvas (no upload, even offline) - your image never leaves your device. The transform is exact: applying it twice returns the original pixels. Animated images are flattened to a single frame.

Limitations: Inverts an image's colours by replacing each red, green and blue value with 255 minus itself (a photographic negative); alpha is kept. The original format and dimensions are preserved (PNG keeps transparency; JPEG flattens onto white). Animated inputs are reduced to a single frame. Applying it twice returns the original.
No. The inversion runs entirely locally in the browser on a canvas - even offline. Your image never leaves your device.
Each colour channel becomes 255 minus its value, so black and white swap and every hue becomes its complement - a photographic negative.
Yes. Inversion is its own opposite: running the tool again on the inverted image returns the original colours.
Yes. The alpha channel is left unchanged; only the red, green and blue values are flipped. A PNG keeps its transparency.
