pikepdf is a Python library allowing creation, manipulation and repair
of PDFs. It provides a Pythonic wrapper around the C++ PDF content
transformation library, QPDF. It is used by over 3800 repositories and
90 packages. Most notably, OCRmyPDF (12,400+ stars) uses pikepdf to
graft OCR text layers onto existing PDFs, to examine the contents of
input PDFs, and to optimize PDFs. Additionally, PDFArranger (3000+
stars) depends on pikepdf and is a Python application that provides a
graphical user interface to rotate, crop and rearrange PDFs. It is
important that fuzzing be integrarted into pikepdf as the domino effect
of a high or critical vulnerability in pikepdf would cause numerous
other open source software products to be vulnerable as well.
