Save using PDF Optimizer (Acrobat Pro)
PDF Optimizer provides many settings for reducing the size of PDF files. Some of the PDF Optimizer settings are
comparable to the settings that are available when you create a PDF file using Distiller. 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 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. The space audit results may give you ideas about
where best to reduce file size. You can also reduce the size of your PDF by using the Reduce File Size command.
Note: 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.
Open the PDF Optimizer
❖ To open the PDF Optimizer dialog box, do one of the following:
• In a single PDF, choose File > Save As Other > Optimized PDF.
• When editing an Action Wizard, click Save To options. Then in the Output Options dialog box, select PDF
Optimizer, and click Settings.
Note: PDF Optimizer isn’t available when Reflow is selected in the View menu.
Audit the space usage of a PDF (Acrobat Pro)
Auditing the space usage gives you 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.
1 Choose File > Save As Other > Optimized PDF. The PDF Optimizer dialog box opens.
2 Click the Audit Space Usage button at the top of the dialog box.
You can also audit space usage of a PDF in the Content pane. Choose View > Show/Hide > Navigation Panes > Content.
From the Content pane options menu
, choose Audit Space Usage.
Optimize a PDF (Acrobat Pro)
1 Open the PDF Optimizer dialog box (File > Save As Other > Optimized PDF).
2 To use the default settings, choose Standard from the Settings menu, and then skip to step 6. If you change any
settings in the PDF Optimizer dialog box, the Settings menu automatically switches to Custom.
3 From the Make Compatible With menu, choose Retain Existing to keep the current PDF version, or choose an
Acrobat version. (The options available in panels vary depending on this choice.)
4 Select the check box next to a panel (for example, Images, Fonts, Transparency), and then select options in that
panel. To prevent all of the options in a panel from executing during optimization, deselect the check box for that
panel.
5 (Optional) To save your customized settings, click the Save button and name the settings. (To delete a saved setting,
choose it in the Settings menu and click Delete.)
6 When you are finished selecting options, click OK.
7 In the Save Optimized As dialog box, click Save to overwrite the original PDF with the optimized PDF, or select a
new name or location.
