GDPR Compliant In-Browser PDF Encryption ​

Protect Sensitive Documents Directly in Memory Without Remote Server Storage ​

Under Article 32 of the EU General Data Protection Regulation (GDPR / DSGVO), enterprises and individuals must implement appropriate technical and organisational measures to ensure a level of security appropriate to the risk. Uploading employee payroll, medical records, or customer contracts to public US-based cloud converters often constitutes an unlawful transfer of personal data to third countries.

PDFSeal encrypts your PDF documents with AES-256 directly inside your web browser. Zero file bytes leave your local device.
