Image Compare is a desktop image comparison and visual diff application for Linux and Windows. It is designed for inspecting alternate exports, edits, scans, compressed copies and other images where small visual differences can be difficult to spot.
Two or more images can be viewed side by side, stacked or arranged in a grid. Synchronised navigation makes it easier to examine the same region across several images, while relative synchronisation helps when the source images use different resolutions.
For structural differences between a pair of images, the application can generate a luminance SSIM heatmap and export the result for closer inspection.
This is free and open source software.
Key Features
- Open images with drag and drop, the file picker, command-line arguments or file-manager integration.
- Compare two or more images side by side.
- Arrange several images in a grid.
- Stack images and flip between them while preserving the viewing position.
- Synchronise zoom and panning across all open images.
- Use relative synchronisation to compare equivalent regions at different resolutions.
- Lock individual images when independent zooming or panning is needed.
- Generate luminance SSIM heatmaps to reveal structural differences.
- Export generated heatmaps.
- Switch between colour-managed rendering using embedded profiles and raw rendering.
- Copy image paths, open containing folders and close images from context menus.
