Frequently Asked Questions

Can I batch optimize multiple PDFs in Acrobat Pro XI?

Yes, you can batch optimize PDFs in Acrobat Pro XI by using the Action Wizard. Go to File > Action Wizard > Create New Action, add the 'Save' command, and specify 'Optimized PDF' in the settings to process multiple files at once.

Why is my PDF file size still large after using the PDF Optimizer?

If the file size hasn't decreased significantly, the PDF might already be highly compressed, or it contains high-resolution flattened images and embedded fonts that cannot be further reduced without severe quality loss. Check the 'Audit space usage' button in the optimizer to see what is taking up the most space.

Is there a simpler way to reduce PDF size in Acrobat XI?

Yes, for a quicker but less customizable option, you can go to File > Save As Other > Reduced Size PDF. This applies standard compression settings automatically, unlike the PDF Optimizer which lets you manually adjust image DPI and font embedding.

Are optimized PDFs compatible with older versions of Adobe Reader?

When using the PDF Optimizer, you can specify target compatibility. In the optimizer settings dialog, select the 'Make compatible with' dropdown menu to choose an older version of Acrobat or Reader to ensure your recipients can open the file without issues.
