How this works
Make a signature
Draw it with a mouse, trackpad or finger — or sign a sheet of white paper, photograph it, and upload that. The paper is made transparent so only the ink lands on the document.
Put it where it goes
Click the spot on the page. Adjust the size with the slider, and click a placed signature to take it off again.

The signature is added on top of the page. Nothing else about the document changes.
You do not need a printer
The usual routine for a form that needs signing is to print it, sign it, scan it, and send back a crooked photograph of a piece of paper. The result is larger, harder to read, no longer searchable, and no more meaningful than a signature added digitally.
Signing on the page skips all of that and keeps the document as it was — which is also why the file you send back looks like the file you were sent, rather than a photo of it.
What this is and is not
This places a picture of your signature on a page. That is what the overwhelming majority of documents asking for a signature actually need, and it is what printing and scanning produces too.
It is not a cryptographic digital signature — the kind that embeds a certificate and lets a reader verify the document has not been altered since. If you have been asked specifically for a digitally signed or certified PDF, you need software issued with a certificate, and this is not that.
Why this one particularly should not be uploaded
Signing means handing over two sensitive things at once: a contract, and an image of your signature. A signature image is reusable — it can be placed on any other document by anyone who has it.
Neither leaves your device here. There is no upload, nothing stored, and nothing for us to delete. Check it in the Network tab of your browser’s developer tools, or disconnect from the internet after the page has loaded and sign anyway.
Frequently asked questions
Is my signature uploaded anywhere?
No. Both the document and the signature stay in your browser. You can confirm it in the Network tab of your developer tools, or by disconnecting from the internet after the page has loaded.
Is this a legally valid signature?
It produces the same thing as printing, signing and scanning — an image of your signature on the page. Whether that satisfies a particular requirement depends on the document and your jurisdiction, and this is not legal advice. It is not a certificate-based digital signature.
Can I sign on a phone?
Yes, and a finger on a touchscreen usually gives a better signature than a mouse does.
How do I use a signature I already have on paper?
Sign a blank sheet of white paper, photograph it in good light, and choose “Use a photo”. Light pixels are treated as paper and made transparent, so only the ink is placed on the document.
Can I put the same signature on several pages?
Yes. Click each place it should appear — it can go on as many pages as you need, at different sizes if you want.
Will the document still be searchable?
Yes. The signature is drawn on top of the existing page, so the text underneath is untouched and stays selectable and searchable.
