What is an E-Signature?
An electronic signature (e-signature) is a digital way to indicate consent or approval on a digital document. It replaces the slow process of printing, manually signing, scanning, and emailing paperwork back.
Two Workflow Modes
- Prepare Mode: You are the sender. You drag-and-drop "Signature Boxes" onto the document to show others where they need to sign.
- Sign Mode: You are the signer. You click on the boxes and draw your signature using your mouse, trackpad, or touchscreen.
How to Sign a PDF
- Upload: Open your contract or agreement PDF.
- Place Field: Click "Signature Box" in the sidebar and position it on the signature line.
- Sign: Switch to "Sign" mode, click the box, and draw your name.
- Finish: Click "Finish & Download" to burn the signature permanently into the file.

Frequently Asked Questions
Is this legally binding?
In many jurisdictions (like the US/ESIGN Act and EU/eIDAS), electronic signatures are legally binding for most business documents. However, consult your legal team for specific compliance needs.
Can I type my name instead of drawing?
Currently, we focus on drawn signatures for authentication, but a text-based option is coming soon.
