Before/After Slider FAQ

Common questions about comparing images

How does the before/after image slider work?

Upload two images -- a "Before" and an "After." The tool overlays them in a single container and provides a draggable slider. Drag left or right (or up and down in vertical mode) to reveal each image. The divider shows exactly where one image ends and the other begins.

Can I export the comparison as a single image?

Yes. Click "Export as Image" to download the comparison at the current slider position. The export includes the divider line and, optionally, Before/After labels. Choose PNG, JPG, or WebP format.

Are my images uploaded to a server?

No. Everything runs entirely in your web browser using the Canvas API. Your images are never sent to any server, and no data leaves your device. This ensures complete privacy.

Do the two images need to be the same size?

The tool works best when both images share the same dimensions and aspect ratio. If the images are different sizes, they will be scaled to fit the comparison container. For accurate pixel-level comparisons, use images of identical resolution.

Can I compare images vertically (top/bottom)?

Yes. Toggle the orientation from "Horizontal" to "Vertical" in the settings panel. In vertical mode the slider moves up and down, with the Before image on top and After on the bottom.

Is this tool completely free?

Yes, completely free with no limits, no signup, no watermarks, and no hidden costs. Compare as many image pairs as you like. The tool is funded by optional ads and will always remain free.
