SnapDiff

Compare images with 4 modes: overlay, XOR, heatmap and rectangle marker. Local & privacy-friendly - SnapDiff shows what has really changed.

Can you see the difference? SnapDiff will show you. SnapDiff is your precise tool for visual image comparison - fast, intuitive and completely offline. Developed for developers, designers and anyone who wants to see exactly what has changed between two images.

Four smart comparison modes

• Overlay mode (transparency) Two images are superimposed. Use the slider to adjust the opacity - ideal for quick visual checks when making design or screenshot changes.

• Pixel diff (XOR) All deviating pixels are highlighted. Ideal for UI regression tests and exact comparisons.

• Heatmap diff Stronger changes appear more intense in color. Immediately visible - even with subtle differences.

• Marking (rectangle mode) SnapDiff automatically recognizes changed areas and marks them with red boxes. Perfect for structured screens and clear focus zones.
