Is my file uploaded to a server?

No. This tool runs entirely in your browser via WebAssembly — your file never leaves your device. You can verify this in your browser's DevTools Network tab.

How do I create a signature?

Draw it with your mouse or finger, type your name in a signature font, or upload a transparent PNG — then drag it onto the page.

Is this a legally binding e-signature?

It places a visual signature image on the PDF. It is not a cryptographic/qualified digital signature. Everything happens locally — nothing is uploaded.
