⚙️ Lossless PDF Page Tree Extraction & Custom Range Slicing
When a government portal, accountant, or colleague only needs pages 4–7 of a massive 200-page report, emailing the entire document wastes bandwidth and exposes unrelated confidential chapters.
DH Tools parses the PDF Catalog Page Tree directly in browser memory—allowing flexible range syntax (`1-5, 9, 14-20`), visual single-page extraction, or full document bursting into individual PDFs with 100% vector fidelity.
