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 with pikepdf.open('input.pdf') as pdf: num_pages = len(pdf.pages) del pdf.pages[-1] pdf.save('output.pdf')
pip install pikepdf
For users who want to build from source, see installation.
pikepdf is documented and actively maintained. Binary wheels are available for all common platforms, both x86-64 and ARM64/Apple Silicon.
Commercial support is available.
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.

I decided to try writing a quick Python program with pikepdf to automate [something] and it "just worked". –Jay Berkenbilt, creator of QPDF
"Thanks for creating a great pdf library, I tested out several and this is the one that was best able to work with whatever I threw at it." –@cfcurtis
OCRmyPDF uses pikepdf to graft OCR text layers onto existing PDFs, to examine the contents of input PDFs, and to optimize PDFs.
PDF Arranger is a small Python application that provides a graphical user interface to rotate, crop and rearrange PDFs.
PDFStitcher is a utility for stitching PDF pages into a single document (i.e. N-up or page imposition).
