Setting specific export options for JPEG format

Once you've decided on an export format as described in About export formats, and have chosen the high-level export options as described in Setting basic export options, you can specify document-level settings for JPEG format.

It's a good idea to use the Preview Export Compression command and watch the Composition window and the file size indicators to see how your choices affect the size and visual quality of your composition. (See Previewing compositions.)

To specify export options for JPEG format:

1. Choose the general options for exporting as described in Setting basic export options.
2. Verify that you chose JPEG from the format menu at the top of the Export palette.
3. Specify the quality for the exported image by dragging the Quality slider or by entering a value (0-100) in the text box. Higher values increase the quality as well as the file size of the exported image.
4. Choose any of the following:
• Select Progressive to export the images as a progressive JPEG.
• Select Reduce Chroma to create a slightly smaller JPEG file. If the image quality visibly degrades, increase the Quality setting.
• Select Optimized to create a custom compression table for the image. Optimized JPEGs have a slightly smaller file size and a longer compression time.
