Before and after slider maker
Drop in a before and an after photo, drag the handle, and download the result: a split image for social posts, or an HTML slider you can open anywhere. Everything happens in your browser.
Your photos stay on your device
The slider is built in your browser. The photos are never uploaded, and the downloaded HTML file carries both images inside it, so it works offline and doesn't depend on our servers.
Tips for a clean comparison
Shoot from the same corner at the same height, with the same lens zoom and similar light. Straighten verticals before you start. If you only have a before photo, you can stage or redesign it with AI to make the after.
How it works
Add two photos
Take both from the same spot and height so the slider lines up.
Label and fit
Rename the labels and choose crop or fit if the photos differ in shape.
Preview
Drag the handle (or use the arrow keys) to check the comparison.
Download
Save a PNG split image, or a single HTML file with a working slider.
Questions
Are my photos uploaded?
No. The maker runs entirely in your browser. Exports are created on your device and downloaded directly.
How do I put the slider on my website?
Download the HTML slider and host the file on your site, or open it and copy its contents into a page. It has no external dependencies.
What if my photos are different sizes?
The frame follows the before photo. Choose 'Crop to fill' to crop the after photo to match, or 'Fit whole photo' to show all of it with white bars.
Can I make an 'after' photo here?
Yes, with a free account: the AI redesigns your before photo into an after. Building the slider itself is free and needs no account.
