Optimization options for GIF and PNG-8 formats

GIF is the standard format for compressing images with flat color and crisp detail, such as 
line art, logos, or illustrations with type. You can lower the size of GIF images by reducing 
the number of colors in the file. Like the GIF format, the PNG-8 format efficiently 
compresses solid areas of color while preserving sharp detail; however, not all Web 
browsers can display PNG-8 files. PNG-8 settings are very similar to the GIF settings. 
(See 

“About file formats” on page 453

.)

Optimization panel for GIF format: 

A.

 File format menu

B.

 Color Reduction Algorithm menu

C.

 Dither Algorithm menu

D. 

Transparency dithering menu

E.

 Optimize menu 

Note:

 In ImageReady, you can control which options show in the Optimize palette by 

clicking the Show Options control 

 on the Optimize palette tab. To show all options, 

choose Show Options from the Optimize palette menu.

Lossy (GIF only)

Specify a Lossy value to allow for lossy compression. Lossy compression 

reduces file size by selectively discarding data—a higher Lossy setting results in more data 
being discarded. You can often apply a Lossy value of 5–10, and sometimes up to 50, 
without degrading the image. File size can often be reduced 5%–40% using the Lossy 
option. 

You can use masks from type layers, shape layers, and alpha channels to vary lossy 
compression across an image. This technique produces higher-quality results in critical 
image areas without sacrificing file size. (See 

“Using weighted optimization” on page 428

.)

Note:

 You cannot use the Lossy option with the Interlaced option or with Noise or Pattern 

Dither algorithms.

Color Reduction Algorithm and Colors

Choose a algorithm for generating a color table 

from the Color Reduction Algorithm menu. (See 

“Generating a color table” on page 431

.) 

Then specify the maximum number of colors in the Colors text box. If you choose Web for 
the color reduction algorithm, the Auto option becomes active in the Colors pop-up 
menu. Use the Auto option if you want Photoshop or ImageReady to determine the 
number of colors in the color table based on the frequency of colors in the image.

You can use masks from type layers, shape layers, and alpha channels to vary color 
reduction across an image. This technique produces higher-quality results in critical image 
areas without sacrificing file size. (See 

“Using weighted optimization” on page 428
