PDF Editing and Security Tools
PDF editing tools let you modify documents without converting them back to their original format. Add watermarks, page numbers, passwords, and annotations directly in your browser.
Security tools protect sensitive documents with encryption, password protection, and redaction. Once redacted, sensitive information is permanently removed from the PDF, not just hidden.
These tools use pdf-lib for client-side PDF manipulation. All editing happens locally, ensuring confidential documents are never exposed to external servers.
