Your PDF is opened by this page and never uploaded. It is edited here, in WebAssembly, and the page keeps working with the network off.
Open the PDF that needs your signature, press Sign, and draw it with your finger on a phone or your mouse or trackpad on a computer, or type your name and have it set in a handwriting style. Press Place it and tap where the signature goes; it can be moved and resized after, and placed again on another page for initials. Choose Text to add the date beside it, then download the signed PDF.
The document never leaves your device. Signature sites upload the contract to their servers, and often your signature with it; this page opens the file in the tab and writes the signed copy there, in WebAssembly, and is served with a rule that forbids it from opening a connection to anywhere.
The signature is drawn into the PDF as a picture with a transparent background, so the line and the text under it show through, and the rest of the document is left exactly as it was.
How to use it
- Open your PDF. It is never uploaded.
- Press Sign, then draw your signature, or type your name, and press Place it.
- Tap where it goes. Drag it to move it, or its corner to resize it.
- Add the date with Text, then press Download.
Questions
Is a signature made like this legally binding?
In many places a signature you draw or type on a document is a valid electronic signature for everyday agreements, such as leases, forms and consent letters, under laws like the US ESIGN Act and the EU's eIDAS rules. Some documents need a certified digital signature or a witness instead, so check with whoever asked you to sign. This page puts your signature on the page; it does not add a cryptographic certificate.
Can I sign on my phone?
Yes, and it is the easiest way to draw one: the signature pad takes your finger. Tap the page to place the signature, and use two fingers to scroll while the Sign tool is on.
Is my signature saved anywhere?
No. It is kept in the open tab so you can place it on several pages, and it is gone when you close it. Nothing is stored in the browser or sent anywhere.
Is my PDF uploaded?
No. The document is opened by this page, drawn by a PDF renderer in the tab and written back out by WebAssembly on your device. The page is served with a rule that forbids it from opening any network connection, so the file cannot leave your computer or phone.

Your data stays on your device
Everything above runs inside your browser as WebAssembly compiled from Rust. Nothing you type is uploaded, logged or stored on a server. You can load this page once, go offline, and it still works.
This page makes no requests at all, to anywhere. That is not a promise in the copy: it is a Content-Security-Policy header your browser enforces, and connect-src on it is none. Open the network tab and watch nothing happen.
