Why use our Comparison Slider?
Compare visual shifts in detail with a smooth, browser-rendered split handle.

Frequently Asked Questions
Explore comprehensive answers, technical specifications, and helpful guidance for organizing and managing your documents.
How does the before-and-after image comparison slider work?
Upload two images of identical dimensions (original and edited) to interactively slide across the split boundary and inspect adjustments.
Can I export the interactive before-after slider comparison?
Yes. You can export side-by-side composite images or snapshot comparisons for client presentations and design showcases.
What image formats are supported for comparison?
JPEG, PNG, WebP, GIF, and BMP pairs can all be loaded into the comparison viewport. Images are matched by dimensions for the slider view, and any pair of exports from this site, such as a compressed original beside its optimized result, works perfectly.
Is my comparison data kept private?
Yes. Both images are read into local browser memory and rendered in a draggable split viewport. No comparison, filename, or pixel data is transmitted anywhere, so confidential designs and unreleased product shots stay entirely on your machine.
