Image Compare Tool
Compare two images side-by-side with a drag slider — perfect for before/after edits, photo revisions, or spotting differences.
About this tool
Upload two images and drag the slider to reveal one over the other — a fast way to check before/after edits, compare photo revisions, or spot what changed between two versions of an image. Everything happens locally in your browser; neither image ever leaves your device.
How to use it
- Upload your "before" image on the left and your "after" image on the right.
- Drag the slider handle left and right to reveal more or less of each image.
- Use it to check edits, compare revisions, or present a before/after to someone else.
Tips
- For the cleanest comparison, use two images with the same dimensions and framing.
- Works great for photo edits, design revisions, before/after transformations, or product shots.
FAQ
Can I compare two differently sized images?
Yes — the slider still works, but for the clearest comparison it helps if both images share the same dimensions and framing.
Are my images uploaded anywhere?
No. Both images are read and rendered entirely in your browser using local file APIs — nothing is sent to a server.
