PDF WorkBench

PDF Workbench is a complete, private PDF toolkit that works entirely on your device.
Upload a PDF once — or paste a link, or scan with your camera — then apply as many tools as you like. Your files never leave your phone. No sign-up, no uploads, no tracking.

ORGANISE • Merge, split (by page/range), reorder, extract, delete pages • Insert another PDF; scan pages with your camera into a PDF

CONVERT • Compress; Images↔PDF; PDF → JPG/PNG/Word/PowerPoint/Excel/Text • OCR
scanned pages to text, on-device (beta)

EDIT • Add/edit text, white-out, images and logos • Watermark (text or image; diagonal, centre or tiled; any colour & opacity) • Letterhead — apply a template behind or over pages, with drag/resize adjustment • Header & footer, page numbers, Bates numbering, rotate, crop, resize to A4/Letter

FORMS & SECURITY • Fill and flatten PDF forms • Sign — draw or type, save signatures for reuse, add a dated caption • Stamp — APPROVED/DRAFT/CONFIDENTIAL/PAID and more,
custom dated stamps, save your own presets • Redact / mask, with one-tap auto-masking of Aadhaar and PAN numbers • Unlock PDFs you own

WHY PDF WORKBENCH • 100% private — processed in your browser, never uploaded • Works offline once installed; searchable tool hub with favourites • Light & dark themes • Fast, clean, and free

A note on honesty: signatures, stamps and redaction are visual (burned into the page). True password encryption, certificate-based digital signatures, and pixel-perfect Office conversion need a server and aren’t included. Everything else works on-devicE
