Sign PDF
Draw your signature once, then click to place it anywhere in the document. Signature and file both stay on your device.
1. Draw your signature
Use your mouse, trackpad or finger. It stays on your device like everything else here.
- 01Draw your signature on the pad with a mouse, trackpad or finger. The background is removed automatically.
- 02Open the PDF and click wherever the signature belongs — drag to fine-tune, use the slider to size it.
- 03Click Save. The signed PDF is assembled on your device and downloads immediately.
A signature is the one thing on a document that is unambiguously yours — and the standard online workflow asks you to upload it, along with the agreement it belongs to, to a server you know nothing about. That trade never made sense, and here it doesn't happen.
ZorPDF's signing flow is deliberately simple: draw, place, save. It covers the everyday reality of signatures — leases, permission slips, engagement letters, delivery confirmations — where what's needed is your mark on the page, not a certificate chain. The whole process runs in your browser, so the signed file exists in exactly one place: your device.
Is this a legally binding electronic signature?+
It places a drawn signature image into the document — the same as printing, signing and scanning, and widely accepted for everyday agreements. It is not a cryptographic digital signature (the kind with certificates); for those, regulated providers are required. For the common 'sign and send back' case, this does the job in seconds.
Where does my signature go after I draw it?+
Nowhere. It exists as an image in your browser tab while you work and is embedded into the PDF on your device. When you close the tab it's gone — we never see it, and there's no account storing it.
Can I sign in more than one place?+
Yes. Click everywhere a signature is needed — initials on every page, full signature at the end. Each placement can be dragged into position, and the size slider controls how large it appears.
Why does the signature background disappear?+
The tool automatically removes the white background from your drawing, so the signature lays over the document like ink rather than a white sticker.
