PDF Security & Metadata
Analyze your PDF security status, check encryption, and edit document metadata — all privately in your browser.
All processing is performed client-side. Your PDFs never leave your device.
Important: Full PDF password encryption requires server-side processing and is not supported in the browser with pdf-lib. This tool can analyze your PDF's security status and update metadata. For full encryption, consider using a desktop tool like Adobe Acrobat or qpdf.
