Colour and tone

Adjust image colours

Tune exposure, brightness, contrast, saturation, hue, temperature, gamma, sharpness, and blur while using a histogram and same-size comparison to judge the result.

Image colour picker

Sample any pixel as HEX, RGB, HSL, and alpha, then extract dominant colours and their shares for design, branding, and visual analysis.

Replace an image colour

Sample and replace a colour with adjustable tolerance and edge feathering, preserve luminance when needed, or make the selected colour transparent.

Compare images

Inspect two images with slider, side-by-side, flicker, and single-image views, then calculate changed pixels, change percentage, and mean pixel error.
