For developers who want to integrate PDF password removal into their own applications (SaaS, automation bots), this Python-based approach is the top GitHub choice. pikepdf (a modern fork of PyPDF2) essentially wraps QPDF in Python.

import pikepdf
with pikepdf.open("locked.pdf", password="") as pdf:
pdf.save("unlocked.pdf")
