How can I read the properties/metadata like Title, Author, Subject and Keywords stored on a PDF file using Python?
Try pdfminer:
from pdfminer.pdfparser import PDFParser
from pdfminer.pdfdocument import PDFDocument
fp = open('diveintopython.pdf', 'rb')
parser = PDFParser(fp)
doc = PDFDocument(parser)
print(doc.info) # The "Info" metadata
Here's the output:
>>> [{'CreationDate': 'D:20040520151901-0500',
'Creator': 'DocBook XSL Stylesheets V1.52.2',
'Keywords': 'Python, Dive Into Python, tutorial, object-oriented, programming, documentation, book, free',
'Producer': 'htmldoc 1.8.23 Copyright 1997-2002 Easy Software Products, All Rights Reserved.',
'Title': 'Dive Into Python'}]
