Remove Hidden Information options
Metadata Metadata includes information about the document and its contents, such as the author’s name, keywords,
and copyright information, used by search utilities. To view metadata, choose File > Properties.
File Attachments Files of any format can be attached to the PDF as an attachment. To view attachments, choose View
> Show/Hide > Navigation Panes > Attachments.
Bookmarks Bookmarks are links with representational text that open specific pages in the PDF. To view bookmarks,
choose View > Show/Hide > Navigation Panes > Bookmarks.
Comments And Markups This item includes all comments that were added to the PDF using the comment and
markup tools, including files attached as comments. To view comments, choose the Comments pane.
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 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.
