Unlock PDF Files - Remove Permission Restrictions
Remove permission restrictions from PDF files for free with AstraPDF's secure online tool. Enable printing, editing, and copying for PDFs that have owner password restrictions. Perfect for accessing your own documents when you need full functionality without limitations.
Our tool removes owner password restrictions (printing, editing, copying limitations) while maintaining complete privacy - all processing happens directly in your browser. No uploads, no tracking, completely free.
Important: What This Tool Does
This tool removes owner password restrictions (printing, editing, copying limitations) from PDFs. It works for PDFs that you can open without a password but have restricted actions.
Limitation: This client-side tool cannot remove user passwords(passwords required to open PDFs). User password removal requires server-side processing for security reasons.

Types of PDF Protection
Owner Password / Permission Restrictions✅ Supported
These are restrictions that prevent certain actions like printing, editing, or copying, but don't require a password to open the PDF.
✅ These restrictions can be removed by our tool. The PDF opens normally but has limited functionality.
User Password / Open Password❌ Not Supported
User Password: Requires a password to open the document at all. The entire PDF is encrypted at the file level, making it completely inaccessible without the correct password.
❌ Our client-side tool cannot remove user passwords. This requires server-side decryption which is computationally intensive and more complex. If your PDF asks for a password when you try to open it, this tool won't be able to help.
