pdfinfo - Portable Document Format (PDF) document information extractor (version 3.00)


pdfinfo [options] [PDF-file]


Pdfinfo prints the contents of the 'Info’ dictionary (plus some other useful information) from a Portable Document Format (PDF) file.

The 'Info’ dictionary contains the following values:

title subject keywords author creator producer creation date modification date

In addition, the following information is printed:

tagged (yes/no) page count encrypted flag (yes/no) print and copy permissions (if encrypted) page size file size linearized (yes/no) PDF version metadata (only if requested)


Pdfinfo reads a configuration file at startup. It first tries to find the user’s private config file, ~/.xpdfrc. If that doesn’t exist, it looks for a system-wide config file, /etc/xpdf/xpdfrc. See the xpdfrc(5) man page for details.


Many of the following options can be set with configuration file commands. These are listed in square brackets with the description of the corresponding command line option.
-f number
  Specifies the first page to examine. If multiple pages are requested using the "-f" and "-l" options, the size of each requested page (and, optionally, the bounding boxes for each requested page) are printed. Otherwise, only page one is examined.
-l number
  Specifies the last page to examine.
-box Prints the page box bounding boxes: MediaBox, CropBox, BleedBox, TrimBox, and ArtBox.
-meta Prints document-level metadata. (This is the "Metadata" stream from the PDF file’s Catalog object.)
-enc encoding-name
  Sets the encoding to use for text output. The encoding-name must be defined with the unicodeMap command (see xpdfrc(5)). This defaults to "Latin1" (which is a built-in encoding). [config file: textEncoding]
-opw password
  Specify the owner password for the PDF file. Providing this will bypass all security restrictions.
-upw password
  Specify the user password for the PDF file.
-cfg config-file
  Read config-file in place of ~/.xpdfrc or the system-wide config file.
-v Print copyright and version information.
-h Print usage information. (-help and --help are equivalent.)


The Xpdf tools use the following exit codes:
0 No error.
1 Error opening a PDF file.
2 Error opening an output file.
3 Error related to PDF permissions.
99 Other error.
