Optimizing for the web

Optimization options appear on the right side of the Save For Web dialog box. In addition to selecting a web file 
format, you can choose compression and color options, preserve background transparency or set background matting, 
and change the size of the image. You can use predefined settings (by choosing a format from the Preset menu), or 
select format-specific options to fine-tune the optimization.

The image windows show your original image (on the left) and a preview of the optimized image (on the right). Under 
each window is optimization information—the current settings, the size of the optimized file, and the estimated 
download time. As you make adjustments, the information under the optimized image changes to reflect your new 
settings.

A small toolbox is located in the upper-left corner of the dialog box. To view different areas of an image, select the 
Hand tool 

 and drag to bring those areas into view. To zoom in on an image, select the Zoom tool 

 and click in 

a view; then hold down Option, and click again to zoom out. (Alternatively, you can use the Zoom box at the bottom 
of the dialog box.) To create matte colors, use the Eyedropper Color tool.

You can choose between four formats for the web. Use the following guidelines when choosing the format for your 
web image:

In most cases, this is the best format in which to save photographs.
