Before After Slider — Free Image Comparison Slider Tool

A before/after slider is the clearest way to show an edit: one image, one handle, drag to reveal the change. Upload a before image and an after image, drag the slider to compare them, switch between horizontal and vertical splits, and download a side-by-side PNG for sharing. Everything runs in your browser — your images never leave your device.

Before / After Slider

Drag one handle to reveal the change — edits, renovations, retouches.

How it works

Upload a before image and an after image, then drag the handle (or the slider below) to wipe between them. Horizontal splits reveal left-to-right; vertical splits reveal top-to-bottom. Labels mark each side, and the Download Side-by-Side PNG button exports both images next to each other at full resolution for posts, listings, and portfolios. Your images never leave your browser.
