About This Tool

Purpose and value: This tool provides a visual comparison workspace for image edits, enabling teams to quantify and inspect differences between base and edited variants. It supports multiple inputs, diff modes, and export options to streamline review cycles. Conceptually, it aligns two or more images and computes pixel-level or perceptual differences to produce actionable outputs. Audience includes designers, photographers, QA, and marketing teams who need objective evidence of changes. Unique value lies in rapid diffs, clear diff visualizations, and an exportable report suitable for reviews. Core features include image upload, alignment controls, pixel-diff calculations, perceptual-diff scoring, overlay generations, and export of images and JSON results. Use cases range from versioned edits in a creative pipeline to client review sprints and A/B visual testing.

Export results as images and a JSON report for sharing.

Frequently Asked Questions

Find Quick Answers

What formats are supported?

Supported raster formats include PNG, JPG, and WebP; the tool reads local files or URLs. Vector formats are not analyzed; images with transparency are preserved in diff outputs.

Can I compare more than two images?

Yes. You can compare a base image against multiple variants, generating pairwise diffs and an aggregated summary. This supports batch review workflows and consistent reporting across variants.

How are differences quantified?

Differences are computed with pixel-based metrics (MSE, RMSE, DSSIM) and optional perceptual color differences. Outputs include a diff image, a heatmap, and a numerical similarity score from 0 to 1.

Is data saved locally or on cloud?

Data is kept in the browser session unless you export results. You can download images and a JSON report or copy results; no automatic cloud storage is performed unless you opt in.
