Apply a preset optimization setting
You can quickly and easily optimize an image for the web by choosing a predefined optimization setting, called a preset,
from the Preset menu near the upper-right corner of the Save For Web dialog box. Presets are tailored to meet the
optimization needs of different types of images.
The name of each preset reflects its file format and quality level. For example, choose JPEG High to optimize an image
in JPEG format with high image quality and low compression. Choose GIF 32 Dithered to optimize an image in GIF
format, reduce the number of colors to 32, and apply dithering.
1 In the Save For Web dialog box, choose a setting name from the Preset menu, and then click OK.
2 In the Save Optimized As dialog box, type a filename and click Save.
Note: If you change the options in a preset, the Preset menu displays the word “Custom.” You cannot save a custom
setting; however, the current settings appear in the Save For Web dialog box the next time you display it.
Optimize as JPEG
JPEG is the standard format for compressing photographs.
1 In the Edit workspace, open an image and choose File > Save For Web.
2 Choose JPEG from the optimization format menu.
3 To optimize to a specific file size, click the arrow to the right of the Preset menu, and then click Optimize To
File Size. Enter a number in the Desired File Size text box, and select either Current Settings, which optimizes for
the current settings, or Auto Select GIF/JPEG, which automatically determines whether JPEG or GIF is the better
format.
4 Do one of the following to specify the compression level:
• Choose a quality option (Low, Medium, High, and so on) from the pop-up menu under the optimization format menu.
• Click the arrow in the Quality menu and drag the Quality pop-up slider.
• Enter a value between 0 and 100 in the Quality box.
The higher the Quality setting, the more detail is preserved in the optimized image, but the larger the file size. View
the optimized image at several quality settings to determine the best balance between quality and file size.
