If you don’t want to perform JPEG lossy compression on your site’s images, there’s always the alternative: lossless compression. If you’re more experienced in editing images using lossy compression, there is a chance you can save the image quality while reducing its file size by working with RAW JPEG images, making edits, and saving the image one time. The more editing and saving of a single image you do, the worse the quality of the image will be.When you compress an image using lossy compression, you determine the file size and image quality trade-off ( e.g., smaller files = worse image quality).JPEG lossy compression is usually used for photographs and complex still images.During the compression process, each pixel is compared to pixels surrounding it in a ratio ranging from 2:1 all the way to 100:1 ( any pixels that are the same as the original are then deleted as they are deemed redundant).Image quality does suffer, though it’s often so slight the average site visitor can’t tell.The file size of the image being compressed is permanently reduced by eliminating unnecessary ( redundant) information from the image.Here are some things to remember about lossy compression: JPEG is a lossy compression method used to ensure the digital images being used are as small as possible and load quickly when someone wants to view them. In fact, all website owners should optimize their images in some way to reduce the file sizes of their images and preserve loading times and the user experience. When you upload images to your website, it’s important you take care not to negatively affect your site’s speed and performance by using large images that waste resources and take forever to load on the frontend of your site.
