You can use masks from type layers, shape layers, and alpha channels to vary the quality

level across an image. This technique produces higher-quality results in critical image

areas without sacriﬁcing ﬁle size. (See “

Using weighted optimization” on page 428.)

Optimized Select Optimized to create an enhanced JPEG with a slightly smaller ﬁle size.

The Optimized JPEG format is recommended for maximum ﬁle compression; however,

some older browsers do not support this feature.

Progressive Select Progressive to create an image that displays progressively in a Web

browser. The image will display as a series of overlays, enabling viewers to see a low-

resolution version of the image before it downloads completely.

Note: Progressive JPEGs require more RAM for viewing, and are not supported by some

browsers.

Blur Specify the amount of blur to apply to the image. This option applies an effect

identical to that of the Gaussian Blur ﬁlter and allows the ﬁle to be compressed more,

resulting in a smaller ﬁle size. A setting of 0.1 to 0.5 is recommended.

ICC Proﬁle Select ICC Proﬁle to preserve the ICC proﬁle of the artwork with the ﬁle. ICC

proﬁles are used by some browsers for color correction. (See “

Setting up color

management” on page 104.)

Matte Specify a ﬁll color for pixels that were transparent in the original image:

• Click the Matte color swatch and select a color in the color picker.

• Choose an option from the Matte menu.

Pixels that were fully transparent in the original image are ﬁlled with the selected color,

pixels that were partially transparent in the original image are blended with the selected

color.

Preserve EXIF Metadata (ImageReady) Select to preserve metadata from a digital

camera.

Optimization options for PNG-24 format

PNG-24 is suitable for compressing continuous-tone images; however, it produces much

larger ﬁles than JPEG format. (See “

About ﬁle formats” on page 453.)

The advantage of using PNG-24 is that it can preserve up to 256 levels of transparency in

an image. To save an image with multilevel transparency, select Transparency. For more

information on the Interlaced, Transparency, and Matte options, see “Optimization options

for GIF and PNG-8 formats” on page 420.

Optimization options for WBMP format

WBMP format is the standard format for optimizing images for mobile devices, such as cell

phones. WBMP supports 1-bit color, which means that WBMP images contain only black

and white pixels.

Choose an option from the Dither Algorithm menu to determine the method for

converting pixel values to black or white:

• No Dither applies no dither to the image.

• Diffusion applies a random pattern that is usually less noticeable than Pattern dither.

The dither effects are diffused across adjacent pixels. If you select this algorithm, specify

a Dither percentage to control the amount of dithering that is applied to the image. You

can use masks from type layers, shape layers, and alpha channels to vary the Dither
