This is useful when comparing images that are degraded, for example through a lossy change in size or image-format.Ĭan you diff images of different size or format? A higher value for the Fuzz means, that differences have to be bigger in order to be shown. A Fuzz of 0 means that anyĭifference, no matter how small, will be shown. The Fuzz value describes how tolerant the comparison should be. The Highlight Color is the color in which, as the name suggests, the differences between the images will be highlighted.

The two options we offer are “Highlight Colour” and “Fuzz”. What are the “Highlight Colour” and “Fuzz” options? It actually offers a an incredible amount of additionalįunctionality for image comparison compared to what we use here, so if you need anything more we really recommend that you use the library directly.

The image-processing library we use for this is the ImageMagick Library. Which underlying software do you use to diff the images? That's why we built this little site – it's intended to allow you to quickly compare some images without the hassle of manually using a library.

That can be quite frustrating when you just want to find out what the differenceīetween two images – you have to install the software, work out what parameters to use on the command-line etc.

There are numerous software-libraries out there that allow you to calculate such diffs of images, but most of them are just intended for use from the command line or inside some software. As you can see the differences are nearly invisible for the naked eye, but easily recognizable for a machine.
