Extract / modify PDF metadata (using pdftk)

January 4th, 2010 |

Author: Miguel

PDFTK is a free, open source PDF toolkit. It is one of my preferred tools to deal with pdf metadata. It runs in Windows and Linux platforms.

For instance, you can read the pdf metadata:

$ pdftk original.pdf dump_data output data.txt
$ cat data.txt
InfoKey: Creator
InfoValue: Writer&#0;
InfoKey: Producer
InfoValue: OpenOffice.org 3.1&#0;
InfoKey: CreationDate
InfoValue: D:20090923135542+02'00'

PdfID1: e5d831c33f77ac694b32456732f2c86
NumberOfPages: 1

And you can also modify the pdf metadata:

$ pdftk original.pdf update_info data.txt output resultado.pdf

Note the data.txt must be in a correct format!

Hi Miguel,

you can also use pdfinfo from the Xpdf suite (http://www.foolabs.com/xpdf, Windows & Linux), it’s great:

>> pdfinfo document.pdf
