Sign PDF FAQ

Is this a legally binding digital signature?

No, and that distinction matters more than anything else on this page. What this does is draw your signature onto the document — the electronic equivalent of signing a printout and scanning it back in, which is what most requests to "sign this PDF" actually mean and what every free signing tool offers. What it is not is a certificate-based digital signature: there is no cryptographic proof of who signed, and no seal that would reveal an edit made afterwards. If a contract requires a verifiable signature, you need a service that issues certificates, and no tool that runs entirely in your browser can be one.

Why can I draw *and* type?

Because each is useless on some devices. A signature drawn with a mouse looks nothing like a real hand; on a phone or a tablet, drawn with a finger or a stylus, it looks exactly like it. Typing is legible everywhere and is genuinely your name, if not your handwriting. Offering only one would have made the tool pointless on half the devices that reach it.

How do I get it in the right place?

The page is rendered and you put the signature on it — click where it goes, or drag it until it sits on the line. A corner-and-margin picker, which is how the page-numbering tool works, cannot express "just above the printed name", and that is where signatures live. Position is stored as a share of the page rather than in pixels, so what you see on the preview is where it lands whatever the paper size.

Does signing change anything else in the document?

No. The signature is one image drawn over one page; nothing is decoded, re-encoded or rebuilt, so bookmarks, internal links and fillable form fields all survive and every page stays exactly as sharp as it was. Pages the scanner marked sideways get the signature where you put it rather than up the edge, because the placement is measured in the frame you are looking at.

Can someone remove the signature afterwards?

Yes, with a PDF editor — and that is true of every tool that signs this way, ours included. A drawn signature is an object on a page, not a lock on the file. It records intent, which is what a signature on paper does too; it does not prevent tampering. Anyone who needs the stronger guarantee needs certificates, which is the answer to the first question here.

Is my signature stored anywhere?

It exists in the tab you drew it in and nowhere else. It is not uploaded, not saved between visits and not kept after you close the page — which also means you draw it again next time. Given that the thing being handled is a specimen of your signature, that trade seemed like the right way round.
