pikepdf 0.3.4

Read and write PDFs with Python, powered by qpdf

pikepdf

pikepdf is a Python library for reading and writing PDF files.

pikepdf is based on QPDF, a powerful PDF manipulation and repair library.

Python + QPDF = "py" + "qpdf" = "pyqpdf", which looks like a dyslexia test. Say it out loud, and it sounds like "pikepdf".

# Elegant, Pythonic API
pdf = pikepdf.open('input.pdf')
num_pages = len(pdf.pages)
del pdf.pages[-1]
pdf.save('output.pdf')

To install:

Python 3.5, 3.6 and 3.7 are fully supported.

pip install pikepdf

For users who want to build from source, see installation.

pikepdf is documented and actively maintained. Commercial support is available.

Features

This library is similar to PyPDF2 and pdfrw - it provides low level access to PDF features and allows editing and content transformation of existing PDFs. Some knowledge of the PDF specification may be helpful. It does not have the capability to render a PDF to image.

Python 2.7 and earlier versions of Python 3 are not currently supported but support is probably not difficult to achieve. Pull requests are welcome.
