Using PDF Optimizer
PDF Optimizer provides many settings for reducing the size of Adobe PDF files. Whether
you use all of these settings or only a few depends on how you intend to use the files and
on the essential properties a file must have. In most cases, the default settings are
appropriate for maximum efficiency--saving space by removing some embedded fonts,
compressing images, and removing items from the file that are no longer needed.
Before you optimize a file, it's a good idea to audit the file's space usage to get a report of
the total number of bytes used for specific document elements, including fonts, images,
bookmarks, forms, named destinations, and comments, as well as the total file size. The
results are reported both in bytes and as a percentage of the total file size. The space audit
results may give you ideas about where best to reduce file size.
Important: Some methods of compression may make images unusable in a print
production workflow. You should experiment with various settings before making
changes that can't be discarded.
To audit the space usage of an Adobe PDF file:
1. Do one of the following to open the PDF Optimizer dialog box:
Choose Advanced > PDF Optimizer.
Choose Tools > Print Production > PDF Optimizer.
Click the PDF Optimizer icon
2. Click the Audit Space Usage button at the top of the dialog box.
Note: Optimizing a digitally signed document invalidates the signature.

Choose Tools > Print Production > PDF Optimizer.
Click the PDF Optimizer icon
Note: PDF Optimizer isn't available when Reflow is selected in the View menu.
2. From the Make Compatible With menu, choose a version of Acrobat that the PDF will be
compatible with. (The options available in panels vary depending on this choice.)
3. Select Images on the left, and then select the options you want for color, grayscale, and
monochrome images. (See
4. Select Scanned Pages on the left to balance compression and image quality and apply
filters. (See
5. Select Fonts on the left, and then unembed any fonts that aren't needed, such as system
fonts or fonts that you know are already installed on users' computers. (See
settings.)
6. Select Transparency on the left to implement transparency flattening and set flattening
options. (See
7. Select Discard Objects on the left to select which objects to discard and whether to
convert smooth lines to curves. (See
8. Select Clean Up on the left to set additional compression options, encoding options, items
to be removed or discarded from the file, and whether to apply Fast Web View. (See
Using Clean Up
9. Click the Save button to save and name your customized settings. (You can delete any
saved settings by selecting the file name and clicking the Delete button.)
10. When you are finished selecting options, click OK.
11. In the Save Optimized As dialog box, click Save to overwrite the original file with the
optimized file, or select a new name or location.
Some of the PDF Optimizer settings are comparable to the settings available when you
create an Adobe PDF file using Acrobat Distiller. (See
files.)
To optimize a number of documents at the same time, you can use the Output
Options in the Batch Processing command. (See
