Image Compare is a desktop image comparison and visual diff tool for Linux and Windows. Compare two or more images side by side, stacked, or in a grid with synchronized zoom and pan, and generate perceptual heatmaps to highlight visual differences.
All images zoom and pan together. For different resolutions, relative sync keeps the same proportional region visible in each image.
Use it to choose the best-quality copy, inspect compression artifacts, scans, and exports, compare edited or upscaled versions, and catch subtle changes in color, sharpness, cropping, scaling, or encoding.
