Before and after photo slider

A single-page tool where two photos are dropped in and a draggable handle reveals the differences between them.

The brief

Before and after photos are a common way to show design and photo work. A drag-to-reveal slider lets a viewer compare the two in one frame.

What we built

Built two drop zones for the before and after photos with instant thumbnails.
Made the comparison frame match the first photo's shape, with a draggable handle that reveals the second photo.
Kept everything in the browser, so photos are never uploaded anywhere.

Where it stands

Built in June 2026 as a one-file experiment.
