PDF Redaction in JavaScript: A Practical Guide to Protecting Sensitive Data

PDF redaction permanently removes sensitive information from documents, making it unrecoverable and ensuring compliance with GDPR and HIPAA. Using Syncfusion's JavaScript PDF Viewer, developers can mark text or images for redaction through UI tools or programmatic APIs, customize redaction appearance with colors and overlay text, and apply changes permanently. The guide covers setup steps including CDN integration, enabling redaction tools in the toolbar, and implementing features like shape-based and text-based redaction, full-page redaction, and batch processing through JavaScript APIs.
