The first JPEG standard was issued in 1992 by ISO ( International Organization for Standardization). JPEG stands for the Joint Photographic Experts Group, which is the name of the sub-committee that helped create the JPEG standard, as well as other still picture coding standards under the broader group called ISO. This may result in slower page loading times. While the image quality is never sacrificed because no information is eliminated, know that with lossless compression the final file size of your image will always be bigger than with lossy compression. Lossless compression saves your images in an entirely different format ( usually PNG). 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.
