Whether to remove all output intents

Output intents provide a means for matching the color characteristics of PDF page content with those of a target output device or production environment in which the document will be printed.

Default: except in the profile MinimalFileSize.

Whether to remove the piece-info dictionary (private PDF processor data)

The removal of this proprietary application data has no effect on the document's visual appearance.

Default: except in the profile Archive.

Whether to remove or flatten signature appearances

A signature in a PDF consist of two parts:

• (a) The invisible digital signature in the PDF.
• (b) The visual appearance that was attributed to the signature.

Part (a) can be used by a viewing application, to verify that the PDF has not changed since it has been signed and report this to the user.

During optimizing, the PDF is altered and hence its digital signature (a) is broken and must be removed.

• Flatten: (a) is removed and (b) is drawn as non-editable graphic onto the page. Within the context of signatures this is called "flattening".
• Remove: (a) and (b) are removed.

Default: Flatten in all profiles.

Whether to remove the data describing the logical structure of a PDF

The logical structure of the document is a description of the content of its pages. It consists of a fine granular hierarchical tagging that distinguishes between the actual content and artifacts (such as page numbers, layout artifacts, etc.). The tagging provides a meaningful description, for example "This is a header", "This color image shows a small sailing boat at sunset", etc. This information can be used e.g. to read the document to the visually impaired.

Default: except in the profile Archive.
