PDFs can contain multiple layers that can be shown or hidden. Removing hidden layers removes these layers from the
PDF and flattens remaining layers into a single layer. To view layers, choose View > Show/Hide > Navigation Panes >
Layers.
Embedded Search Index
An embedded search index speeds up searches in the file. To determine if the PDF contains a search index, choose View
> Tools > Document Processing > Manage Embedded Index. Removing indexes decreases file size but increases search
time for the PDF.
Deleted Or Cropped Content
PDFs sometimes retain content that has been removed and no longer visible, such as cropped or deleted pages, or
deleted images.
Links, Actions And JavaScripts
This item includes web links, actions added by the Actions wizard, and JavaScripts throughout the document.
Overlapping Objects
This item includes objects that overlap one another. The objects can be images (composed of pixels), vector graphics
(composed of paths), gradients, or patterns.

Localized patterns appear in the Search panel (Protection > Search & Remove Text).

Change the look of redaction marks (Acrobat Pro)
By default, thin red outlines appear around images and text you mark for redaction, and black boxes appear in place of
redacted images and text. You can set the default appearance of redaction marks before you mark items for redaction.
You can also change the look of redaction marks before you apply the redactions.

• Click the Redacted Area Fill Color icon and select a fill color from the color palette for the boxes that replace
removed items. Choose No Color to leave the redacted area blank.

text alignment.
