A quiet little signing desk

Draw, type, or phone

Three ways to sign: freehand with smooth ink strokes, typed in elegant handwritten fonts, or drawn on your phone's screen — delivered to your desktop device-to-device.

Sign once, place anywhere

Copy and paste signatures with ⌘C / ⌘V, duplicate with one click, drag and resize them down to the smallest initial box.

Built for long documents

Page thumbnails keep you oriented in big contracts, and a red dot marks every page you've already signed.

Real PDF output

Signatures are embedded into the actual PDF — not flattened screenshots. The file you download opens everywhere, exactly as you saw it.

Works offline

Once installed, the extension runs without a connection. Sign on a plane, in a dead zone, anywhere.

Free, forever

No trial, no watermark, no "3 documents per month". There's no server to pay for — so there's nothing to charge you for.

The whole point

Your documents never
leave your device.

Every other PDF-signing service works the same way: you upload your contract — your lease, your medical forms, your offer letter — to someone else's computer, and you trust them with it.

SignetPDF has no server. The PDF is rendered by your browser, signed by your browser, and saved by your browser. Phone signatures travel over an encrypted device-to-device connection. We couldn't read your documents if we wanted to — and we've made sure we never have to want to.

— made with ink & intention

Questions, answered

Is it really free? What's the catch?

Really free. SignetPDF runs entirely on your machine, so there are no servers, storage, or bandwidth costs to recover. No account, no watermark, no limits.

Are these signatures legally binding?

SignetPDF places a visual signature in your PDF — the same as printing, signing, and scanning. For many everyday documents that's exactly what's needed. It does not provide certificate-based digital signatures (e.g. qualified signatures under eIDAS); for those you'll need a certification authority.

How does signing with my phone work without a server?

Your desktop shows a QR code; your phone opens a small signing page and connects straight back to your desktop over WebRTC — an encrypted device-to-device channel. The signature image travels directly between your two devices.

What happens to my PDF after I close the tab?

It's gone. The document only ever lives in your browser's memory while the tab is open. Nothing is stored, cached, or sent.

Does it work with multi-page contracts?

Yes — page thumbnails let you jump around long documents, you can sign as many spots on as many pages as you need, and copy-paste a resized signature across all of them.

Put your name on it.

Free, private, and ready in two clicks.
