pdfinfo

Portable Document Format (PDF) document information extractor (version 3.03)

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)
form (AcroForm / XFA / none)
javascript (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)

The options -listenc, -meta, -js, -struct, and -struct-text only print the requested information. The 'Info' dictionary and related data listed above is not printed. At most one of these five options may be used.

-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.)
-js
Prints all JavaScript in the PDF.
-struct
Prints the logical document structure of a Tagged-PDF file.
-struct-text
Print the textual content along with the document structure of a Tagged-PDF file. Note that extracting text this way might be slow for big PDF files. (Implies -struct.)
-isodates
Prints dates in ISO-8601 format (including the time zone).
-rawdates
Prints the raw (undecoded) date strings, directly from the PDF file.
-enc encoding-name
Sets the encoding to use for text output. This defaults to "UTF-8".
-listenc
Lits the available encodings
-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.
-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.
