Crop Cuts away unwanted portions of the image.
Display with/without preview windows Shows or hides preview
windows of both original and compressed images.
Whenever the optimization settings are changed, both the original file size as well
as estimated download time and the optimized ones are displayed above the
preview windows. This gives you quick reference to judge the desired file size and
download time.
Note: Use the Zoom in mode, and move the mouse over the images in the preview
windows to a specific location. This provides a closer look at the image quality.

Optimizing an image as a JPEG

JPEG Image Optimizer saves your images as JPEGs, which tend to be smaller
than GIF files. The JPEG format is a lossy format, meaning that the more it is
compressed, the more image data is lost. Yet, you can control precisely how much
compression is applied to images in order to get exactly the results you want.
JPEGs support 24-bit colors, so they are especially suitable for photorealistic
images.
To optimize an image as a JPEG:
1. Select Web: Image Optimizer. If objects have been selected, decide how to
save these objects for optimization:
• Entire image Combines all objects and the Web background (or the base
image, depending on which one is displayed on screen).
• Selected objects Saves selected objects as one whole image.
• Selected objects individually Saves selected objects one by one. Image
Optimizer prompts a confirmation message before displaying the next object,
once the saving process of the current displayed object is completed.
2. Select a type of JPEG file from the Preset list or the Mode list on the JPEG
Options tab:
• Progressive Creates an image that gradually fades in as it downloads. This
creates a smaller file, but some browsers may have difficulty displaying it
properly.
• Standard Creates an image compatible with all browsers. But the file is
usually larger than one using the Progressive method.
• Standard Optimized Creates the smallest possible file using a non-
progressive compression technique.
