Put two images next to each other with a draggable slider, a side-by-side split, or a flicker toggle. Perfect for before/after edits, design revisions, product comparisons, photography retouches, and spotting the difference between two versions of the same image. Runs in your browser, so the images you compare (often unreleased designs or edits) stay private.
Slider, split, or flicker — which to use
Draggable slider is the most compelling for before/after on social — viewers drag and see the transformation happen. Great for photography retouches, background removal, and home-improvement content. Side-by-side split is better for design revisions or two-variant comparisons where you need to see both in full at once. Flicker (A/B toggle) flashes between the two images — the fastest way to catch subtle differences the human eye misses in static comparison, used a lot in game art QA and medical imaging.
What makes a good before/after
Matching crop, matching exposure, matching perspective. If the 'after' shot is taken from a slightly different angle or lighting, viewers see the angle change instead of your actual edit. For retouches and AI-enhanced images, keep the source image and edit from the same file rather than re-shooting. For product or home comparisons, lock the camera position (tripod or marked spot) between shots. Then use this tool to drop both into a polished comparison.
Export options
The comparison can be exported as a static image (both halves shown) for blog posts or product pages, or as an animated GIF/WebP that scrubs from left to right for social posts. For interactive embeds, the tool can export an HTML snippet you drop into your site — the slider works natively in any browser. If you want a super-polished before-and-after with a frame, take the exported static comparison and run it through the photo filters for branding.
Common ways people use it
Photography retouching
Show before and after for color grading, skin retouching, sky replacement, or background cleanup.
Design revisions
Compare v1 and v2 of a design for client reviews — slider makes the changes instantly visible.
Home improvement and renovations
Kitchen before and after, room redesign, before-and-after staging — the slider works beautifully for real estate and DIY content.
Product variants
Same product in two color options or two finish levels — comparison sliders are a conversion hack on product pages.
