True Canvas-Burn Redaction vs Surface Overlays

Many basic PDF editors place a black shape over text without removing the underlying characters, allowing anyone to copy or search the hidden details. GS DocSeva performs complete canvas-burn rasterization: each page is decoded into pixels, the selected areas are painted over permanently, and the PDF is rebuilt. The underlying text is completely destroyed and 100% unrecoverable.
