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.

This is not a legally binding electronic signature. It draws a picture of your signature onto the page — there is 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; it does not replace a qualified e-signature service.
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.
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.
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.
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.
These all work the same way — in your browser. Most are free; the ones marked as needing a plan are not.
