About optimizing
When you put images on the web, you need to think about file size. The goal is a file size that is small enough to allow reasonable download times
but that preserves colors and details to your satisfaction.
Three major graphic file formats are used on the web: GIF, JPEG, and PNG. You can optimize images in these formats using one of the following
methods:
To precisely optimize an image for use in web authoring applications, such as Adobe® Dreamweaver®, you can use the Save
For Web command. The Save For Web dialog box lets you preview your image in different file formats and with different
optimization settings. You can also set transparency and animation settings.
For basic optimization, you can use the Save As command. Depending on the file format, you can specify image quality,
background transparency or matting, color display, and downloading method.
Using the Save For Web dialog box
Use the Save For Web dialog box to preview the effects of different optimization options on a photo you want to share on the web. The process is
simple. Open a photo, and choose File > Save For Web. Then choose a format from the file format menu (GIF, JPEG, PNG-8, or PNG-24) and set
options as desired. (The file format menu is directly beneath the Preset menu.) This saves a copy of your file, without overwriting the original
image.

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.
