Pdf Password Remove Github Top Today

To understand why these tools work, you need to know the two types of PDF passwords:

The GitHub tools below handle both, but Owner password removal is instantaneous, while User password removal relies on computational guesswork.

Repo: piotrmaslak/pdf-crack Language: Python Use Case: You don't know the password.

If you have a PDF and you do not know the password, you need a cracker. This repo is a popular Python implementation that attempts to brute-force the password.

GitHub Stars: ~6k combined | Language: Python

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.

Script to remove owner password:

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

This is the cleanest script on GitHub for batch processing thousands of PDFs.
