Sign PDF
Draw, type or upload a signature, then drag it where it belongs.
Runs in your browser. Your document and signature never leave this tab.

What this is, and what it is not
This tool puts a visible signature on a page. That is what the overwhelming majority of everyday agreements actually ask for, and it is exactly equivalent to the common practice of printing a document, signing it, scanning it and emailing it back — with rather better image quality and none of the printing.
It is not a cryptographic digital signature. There is no certificate binding the document to your identity, and no tamper detection: if someone edits the document afterwards, nothing will flag it. If a counterparty has specifically asked for a digital signature, a certificate-based signature, or a qualified electronic signature, they mean something different from this and you will need a service built for it.
Why placement is stored as a proportion
When you drag the signature on the preview, the position is recorded as a fraction of the page rather than a number of pixels. The preview is whatever size fits your screen, so pixel coordinates would mean something different on a phone and a desktop, and different again on an A4 page versus US Letter. Fractions mean that where you drop it is where it lands, on any page size and any screen.
Drawn, typed, or scanned
Drawing with a trackpad rarely flatters anyone, but on a phone or tablet a finger-drawn signature looks genuinely like a signature. Typing renders your name in a handwriting style — quick, legible, and honest about being typed. Uploading a photo of your real signature gives the best result of the three; a PNG with a transparent background is ideal, though a clean white-background scan works too.
Whichever you choose, a drawn or typed signature is cropped to its ink before it is placed, so the mark on the page is the signature itself rather than the signature adrift in a large empty rectangle.
Frequently asked questions
Is my document uploaded when I sign it?
No. The PDF and your signature both stay in your browser tab — the signature is drawn onto the page there and the signed file is handed straight back as a download. Nothing is transmitted. For a document you are signing, that is the whole point: a signature page usually carries your name, address and the terms you are agreeing to.
Is this a legally binding electronic signature?
It produces a visible, handwritten-style signature on the page, which is what most everyday agreements ask for and what a scanned-and-emailed signature amounts to. It is not a cryptographic digital signature — there is no certificate binding the document to your identity, and nothing detects later tampering. If you have been asked specifically for a digital signature or a certificate-based one, you need a service built for that.
How do I create the signature?
Three ways. Draw it with a mouse, trackpad or finger; type your name and have it rendered in a handwriting style; or upload a photo or scan of your real signature. An uploaded image with a transparent or white background works best.
How do I place it exactly where I want?
Pick the page, then drag the signature around the page preview until it sits where you want it. The size slider scales it. What you see on the preview is where it lands in the file, because the placement is stored as a proportion of the page rather than in pixels.
Can I sign a page other than the first?
Yes. Choose any page from the dropdown and the preview follows. Signatures usually belong on the last page, which is one click away.
Does signing change the rest of the document?
No. The existing content is untouched — text stays selectable, images are not re-compressed. Your signature is added as an image on top of the page you chose, and every other page is copied through unchanged.
