Sign PDF
Add your own signature to a PDF, entirely in your browser. Draw it with your mouse or finger, or type your name and have it rendered in a cursive font — either way you get a clean signature you can drag onto any page and resize before saving. This is for signing a document yourself; it doesn't send requests to other people for their signatures, since that would require a server and email delivery.

Frequently asked questions
Can I request a signature from someone else?
Not with this tool — it only adds your own signature to a PDF you already have. Collecting signatures from other people requires sending and tracking requests, which needs a backend service.
Is this a legally binding electronic signature?
It places a visual signature image into the PDF, similar to signing a printed page and scanning it. It does not add cryptographic signing, timestamps, or identity verification, so check your use case's legal requirements before relying on it for contracts.
Is my PDF uploaded to a server?
No. The PDF, your signature, and the merged result all stay on your device — nothing is uploaded.
