JPEG Option Explained

This dialog box will be displayed when saving a file to JPEG format

Do you notice that when you are saving your graphics file as JPEG format, a dialog box comes up asking if you want to save the file in Baseline, Baseline Optimized or Progressive. So which of these is best? First let me explain what is JPEG. JPEG is the file extension, short for 'Join Photographics Experts Group', this is the committee that created the JPEG standard. JPEG is best for dealing with photo when to a certain degree quality is a priority for a significant reduction in size. What does each of these options mean? Baseline (Standard) - This JPEG format is recognized by all Web browsers. Baseline Optimized - This JPEG format option provides optimized color and slightly better compression. It is supported by all modern browsers, but was not supported in the very earliest of Web browsers. It's your best choice for JPEG files today. Progressive - Creates a JPEG file that displays gradually as it downloads, starting out blocky, and gradually getting clearer as it downloads. It doesn't make the image download any faster, but it can give the illusion of speed since the blocky image is loaded right away on a slow connection. By default Baseline (Standard) is selected when you are saving a file to JPEG format
