What Is an Image Comparer?

An image comparer lets you compare two images side-by-side using an interactive slider. Upload an original and an edited image, then drag the vertical divider to reveal differences in real time. Perfect for before/after comparisons, filter testing, and quality checks.

TooliFyra's free online image comparer runs entirely in your browser. Your images never leave your device. No upload, no server processing, complete privacy.

Why Compare Images Side by Side?

Visual comparisons reveal differences that are hard to spot by switching between files. Whether you're evaluating photo edits, checking compression quality, comparing design revisions, or reviewing image restoration results, a before/after slider makes differences instantly visible.
