Why it matters

Side-by-side comparison reveals subtle differences that are impossible to spot by switching between tabs. It is essential for evaluating compression quality, filter effects, retouching work, and any scenario where you need to see exactly what changed between two versions.

Frequently asked questions

What is image comparison?

Image comparison is a technique that displays two images side by side, often with a movable divider, to visually compare differences between them. It is commonly used for before-and-after photos, compression quality analysis, filter effect previews, and version comparisons.

When should I compare two images?

Use image comparison when evaluating compression quality (original vs compressed), previewing filter effects, checking color grading differences, verifying retouching work, or comparing different versions of a design. It is an essential tool for quality control in photography and design workflows.

What image formats are supported?

The tool supports all major web image formats including JPEG, PNG, WebP, GIF, and BMP. Both images can be in different formats — the comparison works regardless of the input format since everything is rendered on canvas.
