Loading Legacy
Unlock PDF removes password protection from a PDF when the user provides the correct password — uses pdf-lib's PDFDocument.load with the password option, falling back to ignoreEncryption for legacy encryption schemes.
Unlock PDF is a high-performance utility designed to help users streamline their workflow. Built with modern web technologies, it ensures fast processing times and high-quality outputs directly in your browser.
Tries PDFDocument.load(buffer, { password, ignoreEncryption: false }) first. On failure, falls back to ignoreEncryption: true (works for legacy encryption). Re-saves without encryption. Browser-based libraries have limited AES-256 support — strong encryption may require desktop software like qpdf.
No. This tool requires you to know the password. It does not break encryption. Use it only on PDFs you own or have permission to modify.
PDFs with strong AES-256 encryption may not be supported by browser-based libraries. If this tool fails, the file likely uses a stronger encryption that requires desktop software.
