PDF password removal requires decryption libraries that cannot run in web browsers due to security restrictions. This tool would need a backend server to decrypt password-protected PDFs. For now, please use desktop PDF tools like Adobe Acrobat, PDFtk, or QPDF to remove passwords from PDFs.

About Unlock PDF

The Unlock PDF Tool provides information about removing password protection from PDF documents. While browser-based PDF libraries have limitations with password removal, this guide explains the process and available options for unlocking password-protected PDFs.

Understanding PDF password removal:

User Password Required - You must know the password to unlock a protected PDF
Owner Permissions - Some PDFs have editing restrictions that can be removed
Encryption Standards - Different encryption levels require different tools
Legal Considerations - Only unlock PDFs you own or have permission to modify
Desktop Tools - Software like Adobe Acrobat, PDFtk, or qpdf for decryption
Command-Line Options - Advanced tools like qpdf for removing restrictions

Browser Limitation: Modern browser-based PDF libraries like pdf-lib cannot remove password encryption due to the complexity of decryption algorithms. For password-protected PDFs, we recommend professional desktop applications like Adobe Acrobat, qpdf, or PDFtk that can handle PDF decryption when you know the password. Always ensure you have legal rights to unlock a PDF before attempting removal.
