Comparison
When to Use Side-by-Side
Side-by-side comparison is the most direct visual technique for spotting differences between two images. Unlike algorithmic diff methods, it relies entirely on the human eye and is therefore ideal for subjective comparisons where "different" is hard to quantify - such as colour grading, UI redesigns, or photography edits.
Use this tool as a first pass before running a pixel-level diff. If the images look identical side by side, the algorithmic tools will confirm with precise numbers. If you already see clear differences, this view lets you communicate them without generating a diff file.
Common Use Cases
UI Design Review
Compare a design mockup alongside its implemented screenshot to verify spacing, colours, and typography match the specification.
Before / After Photography
Evaluate retouching, colour correction, or filter application by viewing the original and edited image simultaneously.
Screenshot Regression Testing
During CI/CD review, manually inspect a baseline screenshot and the latest test screenshot before deciding whether to accept or reject the change.
Asset Version Control
Compare two exported versions of a logo, icon, or illustration to confirm only the intended changes were made and no artefacts were introduced.
