Compare two images
Before and after on top of each other: with the slider you wipe from one image to the other. Or let the page show in red where two versions of a screenshot, plan or photo differ.
Choose two images
or drag both here. The first is before, the second is after.

Left of the line you see before, right of it after. You can also drag directly on the image.
How much a color value must differ for the point to turn red. 0% shows every tiny change, including the traces of JPG compression.
Goes well with: Resize images · Crop image · Compare texts
Both images are only opened in your browser and are never uploaded.
How it works
- 01Choose two images or drag them in. The first is before, the second is after.
- 02Move the slider or drag on the image: before on the left, after on the right.
- 03“Differences” checks both images point by point and colors in red what has changed.
The first image sets the size. If the second has a different size, it is brought to this size; if it has a different aspect ratio, it is stretched in the process, and the page tells you. Very large images are reduced to at most 2,400 pixels on the long side for the comparison.
