Do both images need to be the same dimensions?

For the comparison to align correctly, both images should be the same size and show the same framing/composition.

Can I embed this slider somewhere, or is it just for viewing here?

It's built for creating and viewing the interactive comparison directly — for embedding elsewhere, you'd need a platform that supports this kind of interactive component.

What's this most commonly used for?

Before/after edits, renovation progress, weight loss or fitness progress photos, and product comparisons are all common uses.

Does Image Comparison Slider upload my files to a server?

No. Image Comparison Slider runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

Showing a before-and-after transformation — an edit, a renovation, a progress photo — communicates much more clearly with an interactive slider than with two separate static images side by side. This tool creates a draggable before/after comparison slider from two images, giving viewers direct, interactive control over comparing the two rather than flicking between separate images.
