Image Compare

Image Compare is a desktop image comparison and visual diff tool for Linux and Windows. Compare two or more images side by side, in a stacked view, or in a grid layout, and generate luminance SSIM heatmaps to highlight structural differences between two images.

Use it to compare different versions of the same image, choose the best-quality copy from multiple sources, check compression artifacts, inspect scans or image exports, compare edited or upscaled versions, and catch subtle changes in color, sharpness, cropping, scaling, or encoding.

Open images using drag-and-drop, the file picker, command-line arguments, or a file manager's Open With action
