If you clarify whether you need to remove user password (requires knowing it) or owner password (restrictions only), I can recommend the exact tool and command.

PDF Password Removal: Top GitHub Tools and Projects to Unlock Your Files

We’ve all been there: you have a PDF document that you own, but you can’t remember the "owner password" required to print, edit, or copy text from it. Or perhaps you’re a developer looking to automate the decryption of thousands of files for a data processing pipeline.

While dozens of "freemium" websites offer to unlock PDFs for you, uploading sensitive documents to a random server is a massive security risk. This is where GitHub shines. The open-source community has built powerful, transparent, and free tools that allow you to strip passwords locally on your own machine. 1. The Industry Standard: QPDF

When it comes to PDF manipulation, QPDF is the undisputed heavyweight. It is a command-line program that does structural, content-preserving transformations on PDF files. GitHub Link: qpdf/qpdf

Why it’s a Top Pick: It doesn’t just "crack" passwords; it understands the PDF syntax. If you have a file with "restrictions" (printing/editing disabled) but you can open it, QPDF can create a new version with those restrictions removed instantly. The Command: qpdf --decrypt input.pdf output.pdf Use code with caution. 2. The Python Powerhouse: PikePDF

If you are a developer looking to integrate removal into a script, PikePDF is the most popular library. It is actually a Python wrapper around the aforementioned QPDF, giving you the power of C++ with the ease of Python. GitHub Link: pikepdf/pikepdf pdf password remove github top

Key Feature: It handles even the newest PDF 2.0 encryption standards (AES-256) which many older tools fail to process. 3. The All-in-One Suite: Stirling-PDF

If you aren't a fan of the command line and want a slick, web-based interface that runs locally (via Docker), Stirling-PDF is currently the most trending PDF project on GitHub. GitHub Link: Stirling-Tools/Stirling-PDF

Why it’s Trending: It’s a "bring your own" version of those popular PDF-to-Word websites. You run it in a Docker container, and it gives you a beautiful UI to remove passwords, merge files, and add watermarks—all without your files ever leaving your computer. 4. For the "Forgotten" Passwords: John the Ripper & Hashcat

What if you don't know the password at all? If the PDF is fully encrypted (you can't even open it to read), you need a recovery tool.

The Process: You use a script like pdf2john.py (found in the magnumripper/JohnTheRipper repository) to extract the "hash" of the password.

The Solution: Once you have the hash, you use Hashcat or John the Ripper to brute-force or use a dictionary attack to find the original password. Understanding "User" vs. "Owner" Passwords If you clarify whether you need to remove

Before choosing a tool from GitHub, you need to know what you're fighting:

Owner Password (Permissions): The file opens fine, but you can't print or edit it. QPDF removes this in seconds.

User Password (Open): You can't even see the first page without a password. You will need to provide the password to a tool like PikePDF to save a decrypted copy, or use Hashcat to "crack" it if forgotten. Security Warning

When searching for "PDF password removal" on GitHub, always check the stars and the commit history. Because this is a high-traffic niche, malicious actors occasionally upload compiled .exe files disguised as "unlockers" that are actually malware. Stick to well-known, code-transparent repositories like those listed above.

PDF passwords fall into two categories:

All tools below remove owner passwords (unlock restrictions). None can remove a strong user password without brute-force. pdf password remove github top

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.

❌ What these tools do NOT do:
Crack or recover a lost user password (the one required just to open the PDF). For that, you'd need hashcat/john the ripper against the PDF's hash – which is out of scope here.

Would you like a step-by-step installation guide for any of these tools on your OS (Windows, macOS, or Linux)?

Absolutely. Install QPDF via winget install qpdf or use Chocolatey. The commands are identical to Mac/Linux.
