Image Compare is a desktop image comparison and visual diff tool for inspecting two or more images side by side, in a stacked view, or with a heatmap of perceptual differences.
Use it to compare screenshots, rendered images, exports, design revisions, before and after edits, and subtle visual differences between image versions.
- Side-by-side and stacked comparison
- Grid layout when four or more images are loaded
- Synchronized zoom and pan across images with different dimensions
- Perceptual heatmap generation and export for two same-size images
- Faithful color-profile rendering with an optional raw display mode
- Multiple image formats with fast loading through Qt6 and libvips
