Frequently Asked Questions
Does this tool upload my PDF to a remote server?
No. All decryption runs inside your browser using Web Crypto and WebAssembly. Your files and passwords never leave your computer.
Do I need to know the password to decrypt the PDF?
If the document has an open password, you can enter it or use the Recovery tab to recover a forgotten password. If the file only has print or edit restrictions, the tool strips them without any password.
What encryption standards are supported?
The engine handles AES-256, AES-128, and legacy RC4 encryption across modern and older PDF specifications.
What is the Recovery tab for?
The Recovery tab helps you regain access to your own encrypted documents when you forgot the password. It is built strictly for educational use and recovery of personal files.
How does Assisted Brute Force work?
You can provide known character placements or masks (like "MTH #25"), or specify prefix and suffix hints. The engine only tests combinations that fit your constraints.
Is there a file size limit?
No. Processing happens locally in background Web Workers so your browser stays responsive even with heavy documents.
