Comments And Markups
This item includes all comments that were added to the PDF using the comment and markup tool, including files
attached as comments. To view comments, choose To o ls > Comments.
Form Fields
This item includes Form Fields (including Signature fields), and all Actions and calculations associated with form
fields. If you remove this item, all form fields are flattened and can no longer be filled out, edited, or signed.
Hidden Text
This item indicates text in the PDF that is either transparent, covered up by other content, or the same color as the
background.
Hidden Layers
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 PDF file. To determine if the PDF contains a search index, choose
Tools > Index and then click Manage Embedded Index in the secondary toolbar. 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.
Select a different language version for patterns (Acrobat Pro DC)
Localized patterns appear in the Search panel (Redact > Mark For Redaction > Find Text).
1 Choose Edit > Preferences (Windows) or Acrobat > Preferences (Mac OS).
2 From the Categories on the left, select Documents.
3 In the Redaction area, choose a language from the Choose Localization For Search & Remove Text Patterns menu.
Then click OK.
Change the look of redaction marks (Acrobat Pro DC)
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.
