PDF Tools — Private & Offline

PDF eSign

Privacy-first PDF e-signature. Load a PDF, create a signature (draw, type, or upload), place it anywhere on any page, and export a signed PDF — entirely in your browser. No backend, no uploads.

No PDF loaded

Drag & drop a PDF anywhere on this page, or click to choose one.

Fully private — no uploads, no server. Works offline after the page loads.

How it works

  1. Load PDF — drag & drop or click Open PDF. We validate the file is a real PDF (header check).
  2. Create signature — draw with mouse/touch, type your name in script fonts, or upload a PNG/JPG (white background is made transparent).
  3. Place signature — click “Place signature” then click on the page. Drag to move, corner handle to resize, select + Delete to remove. Works on any page at any zoom.
  4. Export — embeds the PNG into the original PDF via pdf-lib with correct coordinate conversion and downloads as original-signed.pdf.

All processing is client-side. No network calls after page load. Your PDF never leaves your device.
