What is Advanced Shape Redactor?
Advanced Shape Redactor applies custom vector shape masks—including circles, ellipses, freehand polygons, and angled diagonal blackout blocks—to redact sensitive, non-rectangular content in PDF files. When redacting circular corporate seal stamps, angled signatures, blueprint wiring paths, or biometric facial photos where standard rectangular redaction boxes are inadequate, this tool provides versatile geometric redaction shapes. It strips underlying vectors and raster pixels completely, guaranteeing permanent sanitization with zero data leakage across judicial and commercial releases.

Choose your redaction shape tool: Rectangle, Ellipse/Circle, or Custom Polygon.
Step 3
