The speed of website loading is an important part of a successful web strategy. There are two reasons for that. First, the website speed is one of the crucial SEO factors. Second, no online user is ready to wait even extra milliseconds for your website to load. They will quickly go back to the search results page and go to your competitor’s website. In fact, images on your page may hugely decrease the loading speed. That’s why you should consider shrinking them to speed up your website.
Image shrinking can be of two types: lossy and lossless. The first one discards the information from the original file for the sake of size reducing. The second one uses the miracles of modern technologies for preserving the original file quality. This may lead to slightly bigger size than you’ll get through lossy shrinking, but you will have all the original data at packed in the smaller space.
There are plenty of image compressors online, each using their own algorithm and approach to reducing the image size. Today we’ve got a list of 11 image shrinking programs for you, ranging from totally free to paid options, including the online uploaders.
