pyPdf
by 3 othersA Pure-Python library built as a PDF toolkit. It is capable of:
* extracting document information (title, author, ...),
* splitting documents page by page,
* merging documents page by page,
* cropping pages,
* merging multiple pages into a single page,
* encrypting and decrypting PDF files.
By being Pure-Python, it should run on any Python platform without any dependencies on external libraries. It can also work entirely on StringIO objects rather than file streams, allowing for PDF manipulation in memory. It is therefore a useful tool for websites that manage or manipulate PDFs.

Documentation
Documentation of the pyPdf module is available online. This documentation is produced by PythonDoc, and as a result can also be seen integrated with the source code.
Example
from pyPdf import PdfFileWriter, PdfFileReader
output = PdfFileWriter()
input1 = PdfFileReader(file("document1.pdf", "rb"))
# print the title of document1.pdf
print "title = %s" % (input1.getDocumentInfo().title)
# add page 1 from input1 to output document, unchanged
output.addPage(input1.getPage(0))
# add page 2 from input1, but rotated clockwise 90 degrees
output.addPage(input1.getPage(1).rotateClockwise(90))
# add page 3 from input1, rotated the other way:
output.addPage(input1.getPage(2).rotateCounterClockwise(90))
# alt: output.addPage(input1.getPage(2).rotateClockwise(270))
# add page 4 from input1, but first add a watermark from another pdf:
page4 = input1.getPage(3)
watermark = PdfFileReader(file("watermark.pdf", "rb"))
page4.mergePage(watermark.getPage(0))
# add page 5 from input1, but crop it to half size:
page5 = input1.getPage(4)
page5.mediaBox.upperRight = (
page5.mediaBox.getUpperRight_x() / 2,
page5.mediaBox.getUpperRight_y() / 2
)
output.addPage(page5)
# print how many pages input1 has:
print "document1.pdf has %s pages." % input1.getNumPages()
# finally, write "output" to document-output.pdf
outputStream = file("document-output.pdf", "wb")
output.write(outputStream)
outputStream.close()
