Frequently Asked Questions
How does a before/after slider work?
You load two images — the 'before' and the 'after' — and a draggable divider lets anyone reveal one over the other. It's the clearest way to demonstrate edits, repairs, or transformations at a glance.
Do my two images need to be the same size?
For the cleanest result they should share the same dimensions and framing, so the slider aligns the two shots exactly. Crop or resize them first if they don't match.
Are my images uploaded anywhere?
No. The comparison is created entirely in your browser, so neither the before nor the after photo is ever sent to a server — your work stays private.
