The following table compares some of the functionality in PDFs created using the different compatibility settings.

General options for PDF
You can set the following options in the General section of the Save Adobe PDF dialog box:
Description Displays the description from the selected preset, and provides a place for you to edit the description. You
can paste a description from the clipboard. Editing the description of a preset appends the word “(modified)” to the
preset name. Conversely, changing the settings in a preset prepends the description with “[Based on <Current Preset
Name>].”
Preserve Illustrator Editing Capabilities Saves all Illustrator data in the PDF file. Select this option if you want to be able
to reopen and edit the PDF file in Adobe Illustrator.
Note: The Preserve Illustrator Editing Capabilities option counteracts aggressive compression and downsampling. If file size
is a concern, deselect this option.
Embed Page Thumbnails Embeds a thumbnail preview for each page in the PDF, increasing the file size. Deselect this
setting when users of Acrobat 5.0 and later will view and print the PDF; these versions generate thumbnails dynamically
each time you click the Pages panel of a PDF.
Optimize For Fast Web View Optimizes the PDF file for faster viewing in a web browser.
View PDF After Saving Opens the newly-created PDF file in the default PDF viewing application.
Create Acrobat Layers From Top-level Layers Saves Illustrator’s top-level layers as Acrobat layers within the PDF file.
