PDF Markup Tool

The PDF Markup Tool enables structured, plan-driven annotation of PDF documents. It accepts a target PDF and a markup plan detailing actions such as highlight, underline, add_note, redact, and stamp, along with page ranges and coordinates. The system outputs an annotated PDF and a machine-readable markup log. This supports legal reviews, compliance checks, and educational document curation by producing consistent markups across many documents. The underlying workflow parses the plan, maps actions to absolute page coordinates, and renders markups in a deterministic order to ensure repeatable results. It masks redacted regions and preserves non-marked content for auditability. The tool is designed for professionals who require audit trails, precise page-level control, and batch-ready outputs. Its unique value lies in separating content from markup, providing an immutable output alongside a detailed action log, and allowing plan versioning for compliance workflows. Core features include page-range selection, coordinate-based actions, and outputs in PDF plus a JSON log. Use cases include contract reviews, policy updates, and training materials where annotations must be reproduced exactly. The tool emphasizes deterministic rendering, error reporting, and internationalization-friendly coordinate handling to support diverse workflows and jurisdictions.
