How it works

Drag-divider slider

Drag the golden line left and right to reveal either image β€” great for before/after editing comparisons or spotting subtle retouching.

Pixel Diff mode

Every changed pixel is highlighted in red (brighter in B) or blue (darker in B). Useful for catching compression artifacts, watermarks, or hidden edits.

Similarity score

Calculated from the average per-channel difference across all pixels. 100% = identical files. Below 90% means visible differences.

100% private

Runs entirely via the Canvas API. No upload, no server, no tracking. Works offline once loaded.
