1. Choose and check
Add up to 40 images. Natural file-name order creates pairs. Check the previews, swap sides, replace a photo, or delete a group. An odd image remains visible until you add its partner.
ONE STYLE. EVERY PAIR.
Comparison images,
without the repetition.
Turn a folder of photos into a consistent set of before & after images.
Pair, check, and export — your photos stay in this browser.

Files sort naturally by name, then pair two at a time.
JPG, PNG & WebP · up to 40 images · 40 MB and 32 MP per image
No uploads. Original images and file names never leave your device.
Names like 01-before, 01-after, 02-before, 02-after sort alphabetically within each pair. Use Swap to put them on the correct side.
Preparing your batch
TWO USES. ONE WORKFLOW.
A little consistency
goes a long way.
One size, one background, one set of labels. Every comparison looks like it belongs to the same collection.

From folder to finished comparisons.
2. Make it yours
Set the output size, fit or crop, labels, spacing, background and an optional logo. Every preview updates with the shared style. Your logo needs to be selected again in a new session.
3. Export at your pace
Try any pair free. With an active pass, images process one pair at a time into a ZIP. Pause and continue without losing completed results. A damaged image only blocks its own group.
What happens to my images?
All pairing, previews and exports happen on your device. Payment and pass checks contact our server; photos, logos, labels and file names are never sent. Closing this tab clears your images and unfinished export results.
What are the device limits?
Each batch supports 20 pairs, each input supports up to 40 MB and 32 megapixels, and each output supports up to 4096 × 2160 pixels. Large images can still strain browser memory. Resize images first if your device struggles. Encoded results stay in memory until you clear the batch or close the page.
Can I recover a pass on another device?
Use the recovery code from your purchase confirmation on the restore purchase page. Your files stay on their original device. See purchase and refund details for support.
