However there will most certainly be some additional inaccuracy. Use this converter to estimate the size of an image file as you adjust the on-screen image size (in pixels), bit depth (8 bits per byte) and printed dots per. The images will automatically be resized and scaled to the same size before being compared. 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. The difference between these two is that image size designates. A Fuzz of 0 means that anyĭifference, no matter how small, will be shown. Image Resolution, or dpi, is the amount of dots per square inch of an image when it is printed. The Fuzz value describes how tolerant the comparison should be. But whats the difference between DPI and PPI There is much confusion on the subject. The Highlight Color is the color in which, as the name suggests, the differences between the images will be highlighted. PPI and DPI are two important terms describing image resolution. Calculate the dpi achieved by dividing a documents dimension into the. The two options we offer are “Highlight Colour” and “Fuzz”. PIXEL DIMENSIONS are the horizontal and vertical measurements of an image. 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.
High resolution is important for projecting. On a Mac, control+click (or right-click) the image on your desktop. The image-processing library we use for this is the ImageMagick Library. Higher resolutions mean that more pixels are used to create the image resulting in a crisper, cleaner image. What is the resolution of my image On a PC, simply hover over an image on your desktop.

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.
