How PDF Watermark Removal Works

Watermarks in PDF documents are typically embedded using one of three techniques: (1) Stamp & Watermark Annotations stored in the page's /Annots dictionary, (2) Marked Content Artifacts (/Artifact <</Subtype /Watermark>> BDC ... EMC) or diagonal BT ... ET text blocks inside the page content stream, or (3) Light-gray / semi-transparent vector shapes behind darker body text. This tool combines stream-level token filtering with high-DPI luminance thresholding to clean both vector and burned-in watermarks.
