Using predefined optimization settings

The easiest way to optimize an image is to choose a predefined optimization setting. Predefined settings are tailored to meet the optimization needs of different types of images. (See Choosing a file format for optimization.)

The name of each predefined setting reflects its function. For example, choose JPEG High if you want to optimize an image in JPEG file format with High compression quality. Choose GIF 32 Dithered if you want to optimize an image in GIF file format, reduce the colors in the image to 32, and apply dithering.

You can change the options in a predefined setting; however, when the options no longer match the predefined setting, the Settings menu displays the term "Custom." You cannot save a custom setting.

To apply a predefined optimization setting to an image:

Choose a setting name from the Settings pop-up menu.
