Optimizing images is another great way to help reduce the amount of time it takes for a page to load. The 2 levels of image optimization are categorized into basic and advanced.
We’ll use the IP logo weighing in at 32.1 KB for today’s example.
Basic Optimization of JPEG Images
Basic image optimization includes cropping out unnecessary white space. Using the Jpegcrop Windows Application or another image editor, crop out excess white space as illustrated in the screenshot below.
Advanced Optimization of JPEG Images
Advanced image optimization involves lossless compression of the JPEG file. Using the Jpegcrop Windows Application, losslessly compress the image as illustrated in the 2 screenshots below.
Go to Preferences.
Select the following Preference options to compress the JPEG image.
