Client-side electronic PDF signing
Signing sensitive documents such as employment contracts, non-disclosure agreements (NDAs), invoices, and lease contracts requires strict privacy. Unlike conventional cloud signing platforms that store copies of your legal documents on third-party servers, this tool executes 100% locally in your browser sandbox using pdf-lib and HTML5 canvas APIs. Your documents never travel across the internet.
Three flexible signing methods
Create signatures tailored to your needs:
- Draw: Use your mouse, stylus, or finger on touchscreens with realistic ink flow (Black or Formal Blue).
- Type: Enter your full name to generate smooth cursive calligraphy signatures.
- Upload: Upload existing signature images or stamps (PNG with transparency recommended).
Precise multi-page positioning
Navigate through multi-page agreements effortlessly. Drag the signature box to align precisely above the signature line, resize the boundary box to match the document layout, or add multiple signatures across different pages.
Zero server upload guarantee
All cryptographic embedding and PDF modifications run exclusively in client memory. No files, signatures, or metadata are ever logged or uploaded to any remote server.
