Are you one of those people who save your pictures or printscreen’s as a Jpeg file? Did you know that Jpeg’s lose quality each time their re-saved? Well read on below to find out why this happens and to find out a simple yet time consuming solution to fix it.
Simply put, Jpeg’s degrade every save due to their file system, which upon saving, it checks the pixels around each pixel to see how close each color is and if it’s very similar it “groups” them together. This grouping then saves the information about a group of pixels at the same time thus saving space but also losing some of the information on the picture. Every re-save the algorithm re-calculates the pixels of the same color thus grouping more and more into the same groups and creating squarish pattern around the picture.
