Frequently Asked Questions

Is the before/after comparison tool free?

Yes, completely free with no signup and unlimited comparisons.

Can I download or save the comparison?

This tool is for interactive viewing in your browser only — it doesn't export a combined image. To create a shareable before/after graphic, use a collage layout in our Collage Maker instead.

Do the two images need to be the same size?

No, but for the cleanest comparison, images with similar dimensions and aspect ratios line up best. Both images are displayed at the same container size and cropped to fill it.

Does it work on mobile?

Yes. The slider responds to touch swipes on mobile devices just as it does to mouse dragging on desktop.

Are my images uploaded to a server?

No. Both images are loaded and compared entirely in your browser. Nothing is uploaded anywhere.
