Modify PDFs using filters
You can use filters to modify a PDF document by adding effects, changing the color space, and even reducing the size of the file by recompressing graphics.
Choose File > Open, then select a PDF document.
When the file opens, click the Filter pop-up menu at the bottom of the window, then choose a filter.
The effects of that filter are reflected in the window, but the file is not modified.
To step through the pages of the PDF document and see the filter effects on each page, use the navigation arrows in the toolbar.
Click Apply when you want to save the changes.
If you choose Live Update from Filter Inspector, the appearance of the PDF document changes as you select and edit a filter in the filter inspector.
