# View document properties

When you view a PDF, you can get information about it, such as the title, the fonts used, and security settings. Some of this information is set by the person who created the document, and some is generated automatically.

1. Choose File > Properties.
2. Click a tab in the Document Properties dialog box.

### Document Properties

Description

  Shows basic information about the document. The title, author, subject, and keywords may have been set by the person who created the document in the source application, such as Word or InDesign, or by the person who created the PDF. You can search for these description items in Reader to find particular documents. The Keywords section can be particularly useful for narrowing searches.

  Note that many search engines use the title to describe the document in their search results list. If a PDF does not have a title, the filename appears in the results list instead. A file’s title is not necessarily the same as its filename.

  The Advanced area shows the PDF version, the page size, number of pages, whether the document is tagged, and if it’s enabled for Fast Web View. (The size of the first page is reported in PDFs or PDF packages that contain multiple page sizes.) This information is generated automatically and cannot be modified.

Security

  Describes what changes and functionality are allowed within the PDF. If a password, certificate, or security policy has been applied to the PDF, the method is listed here.

Fonts

  Lists the fonts and the font types used in the original document, and the fonts, font types, and encoding used to display the original fonts.

  If substitute fonts are used and you aren’t satisfied with their appearance, you may want to install the original fonts on your system or ask the document creator to re-create the document with the original fonts embedded in it.

Advanced

  Lists PDF settings, print dialog presets, and reading options for the document.

  You can also associate a catalog index file (PDX) with the PDF. When the PDF is searched with the Search PDF window, all of the PDFs that are indexed by the specified PDX file are also searched.

  You can include prepress information, such as trapping, for the document. You can define print presets for a document, which prepopulate the Print dialog box with document-specific values. You can also set reading options that determine how the PDF is read by a screen reader or other assistive device.
