- 2

Sign in the box using your mouse, trackpad, or touchscreen.

Why use this tool
Nothing leaves your device
The signature is embedded locally via WebAssembly — the document is never uploaded.
No printing or scanning
Sign directly on-screen instead of printing, signing by hand, and re-scanning.
Redo it as many times as you like
Clear and redraw your signature until it looks right, at no cost.
Common use cases
Sign a contract
Add your signature to an agreement without printing it out.
Approve a form
Quickly sign off on a form that just needs your signature, not full editing.
Sign from anywhere
Sign a document on your phone or tablet while away from a printer.
Pro tips
- Draw larger and slower for a cleaner signature — small fast strokes can look jagged.
- You can place more than one signature — draw again and drag each one to its own spot, even across different pages.
- Use Request Signature instead if you need to collect signatures from other people with a tracked audit trail.
