Stack two photos and drag the handle in the middle to compare before and after. You can save exactly what you see as a PNG, and the files never leave your device.
How to use it
- Choose the left (before) and right (after) photos
- Drag the handle to move the seam (arrow keys work too)
- If the sizes differ, they are stacked to fit the larger one
- Saving as PNG gives you exactly what is on screen
Common questions
- Do the photos go up to a server?
- No. They are drawn in the browser and saved from here as well. You can cut the internet off.
- What if the two are different sizes?
- They are stacked to fit the larger one. Stretching the smaller one blurs it, but cropping to match would remove the very part you wanted to compare — which is exactly the case when you look at an upscale before and after.
- Does it work on a phone?
- Yes. You can drag with a finger, and with a keyboard the arrow keys move it too.
- What is it for?
- For showing how much changed — retouching before and after, an upscale before and after, a background removed and not.
