Sign a PDF
Draw your signature with a finger or a mouse, drop it where it belongs, and download the signed file. Nothing is uploaded — which matters more here than on any other page of this site.

The document stays on your machine
Held in memory while you work, so a very long document on a phone will be slower than on a laptop. The signature itself is a few kilobytes.
How it works
Three steps, no account, and the document never leaves your computer.
Drop the PDF in
Every page is rendered here so you can find the one that needs signing. Nothing is sent anywhere to do it.
Draw your signature
With a finger on a phone or a mouse on a laptop. Or use a photo of one you signed on paper.
Put it where it goes, and download
Drag it into place, set the size, and save. The signature is drawn onto the page; everything already there is untouched.
What people sign here
A lease or a rental agreement
Full name, address, and often a bank detail or two. The last document anybody should be uploading to a free website they found in a search result.
An employment contract or an NDA
Frequently confidential by their own terms — which an upload to a third party does not obviously respect.
A form that came back as a PDF
School, council, bank, insurer. Print, sign, scan is the usual route and this skips all three steps.
Initialling every page
Some agreements want a mark on each page rather than one at the end. That is a checkbox here rather than forty separate operations.
Why this one should never involve an upload
Every tool on this site runs in your browser, and on most of them that is a nice property rather than a necessary one. Compressing a holiday photo on somebody else's server is not a risk anybody loses sleep over.
Signing is different, and it is worth being direct about why.
What you are handing over
The documents people sign are the ones that identify them. A lease carries your full name, your new address and often your previous one. An employment contract carries your salary. A power of attorney carries rather more than that. Many of them are confidential by their own wording — an NDA that you upload to a third party to sign is a small contradiction.
And then there is the signature itself, which is the one piece of identifying information you cannot change after a leak.
Uploading all of that to a free website, to have a picture placed on a page, is a poor trade. The operation is trivial. The file is not.
The signature is drawn on top, not merged in
What happens here is the same thing that happens with a watermark or a page number: your signature is added to the page as new marks over the existing ones. Nothing underneath is decoded, altered or re-compressed, so the text in the document stays selectable and the file stays the size it was, plus a few kilobytes.
That also means the document you send back is the document you were sent, with something added — rather than a re-printed copy of it.
Drawing it, or photographing it
Drawing with a finger on a phone gives a better result than most people expect, and a mouse gives a worse one. If the mouse version looks wrong, sign a piece of white paper, photograph it, and use that instead.
A photograph brings its background with it, so it lands as a signature on a grey rectangle. Taking the background out first gives a transparent signature that sits on the page properly. Both of those steps also happen on your machine.
What we are not saying
This page puts your signature on the page. Whether a signature made this way is binding depends on the country, the type of document and occasionally on what the other party will accept — some transactions require a witnessed wet signature, some require a qualified electronic signature from a registered provider, and most everyday agreements accept neither of those things nor need to.
We are not in a position to tell you which of those applies to the document in front of you, and any site that tells you it definitely counts is guessing. If the document matters and you are unsure, ask the person who sent it what they will accept.
Nothing is uploaded, and you can check
Load the page, disconnect from the internet, and sign a document. It works. That is the whole demonstration, and it is available on every tool here.
Common questions
How do I sign a PDF?
Drop the PDF onto this page, draw your signature in the box with a finger or a mouse, drag it to where it belongs and download the signed file. The PDF is read from your disk, the signature is drawn onto the page in your browser, and the result is written back to your downloads folder. Nothing is transmitted at any point — you can disconnect from the internet after the page loads and it still works.
Is it safe to sign a contract on a website?
On most sites, that means uploading the contract to a server you know nothing about — and the documents people sign are exactly the ones that identify them: full name, address, salary, bank details. Here the file never leaves your machine, which removes the question rather than answering it. The check is simple: disconnect from the internet after the page loads, and see that it still works.
Can I use a photo of my signature?
Yes. Sign a piece of white paper, photograph it, and load it instead of drawing. One thing to know: a photograph brings its background with it, so it lands as a signature on a pale rectangle. Removing the background first gives a transparent signature that sits on the page properly — and that step also runs on your device.
Does signing change the rest of the document?
No. The signature is drawn onto the page as new marks over the existing ones, exactly the way a watermark or a page number is. Nothing underneath is decoded, altered or re-compressed, so the text stays selectable and the file stays the size it was plus a few kilobytes for the signature image.
Is a signature made this way legally binding?
That depends on the country, the kind of document and sometimes on what the other party will accept. Some transactions need a witnessed wet signature, some need a qualified electronic signature from a registered provider, and most everyday agreements need neither. This page places your signature on the page; it is not in a position to tell you what that is worth for your document, and any site that says it definitely counts is guessing. If it matters, ask whoever sent it what they accept.
Can I put my signature on every page?
Yes, with the checkbox. It goes in the same position on every page, which is what agreements asking for initials throughout are usually after. If different pages need it in different places, sign one page at a time instead.
Why can it not open my PDF?
The usual reason is password protection: an encrypted document cannot be read without the password, and this page does not ask for one. Open it in any PDF reader, save an unprotected copy, and sign that. A file that is not really a PDF despite its name will also be refused.
Does it work on a phone?
Yes, and drawing with a finger gives a noticeably better signature than a mouse does. A long document is held in memory while you work, so a hundred-page contract will be slower on a phone than on a laptop.
