Your file never leaves this browser

Sign a PDF

Draw your signature with a mouse or a finger, or type your name, then click on the page where it belongs. The signature is drawn into the page itself and the file comes back ready to send. It all happens on your own machine, which is the point: a document worth signing is a document worth not uploading.

Questions

Is this a legally binding electronic signature?

No, and it is important to be clear about that. This draws a picture of your signature onto the page. It carries no certificate, no timestamp and no tamper detection, so it cannot prove who signed or that the file has not changed since. It replaces printing, signing and scanning — not a qualified e-signature service.

Can the signature be removed again?

Not easily by accident: it is written into the page content, so it survives being emailed, printed and re-saved. But anyone determined can edit a PDF, which is exactly why this is not proof of anything. Treat it as ink on paper, with the same strengths and the same limits.

Is my document uploaded to be signed?

No. The page is rendered and the PDF is rewritten inside your browser. Open your network tab while you use it: nothing goes up. The signature you draw never leaves the tab either.

Why does my typed signature look different on another computer?

A typed signature is drawn using a handwriting font your own system already has, and then turned into a picture before it goes into the PDF. The picture is fixed, so the file looks the same everywhere — but two people typing the same name may start from different fonts.
