Sign a PDF

Draw your signature, click where it goes, download the signed document. Nothing is uploaded — which matters more here than anywhere else on this site, because an image of your signature is reusable by whoever holds it.

Sign as many pages as you need. The signature goes on as a transparent image, so the text underneath stays selectable and nothing is re-rendered.

Nothing is uploaded. The document, the drawing and the signed result never leave this tab.

Why this one should never be an upload

Every other signing service works the same way: you draw your signature in their browser window, it is posted to their server, and the server stamps it onto your document. Both halves go up — the contract and the signature.

A signature is not like other data. It is not a password you can change, and it is not a document that becomes stale. It is a reusable mark that identifies you, and an image of it can be applied to any other document by anyone who has it. Handing that to a service, in exchange for a job that is a canvas element and some coordinate arithmetic, is a bad trade at any price — and most of these services are free, which tells you something about what they are actually collecting.

Here the drawing stays a canvas in your tab, the document stays an array of bytes in your tab, and the signed file is assembled between them. You can watch the Network tab the entire time.

Electronic, digital, and qualified

Three different things that get used interchangeably, and the difference decides whether this page is the right tool.

What it isProves
Electronic signature A mark on the page showing intent to sign. This page. That somebody signed
Digital signature A cryptographic certificate embedded in the file That the file has not changed since signing
Qualified signature A digital signature from an accredited trust provider Identity, verified by a third party

For an NDA, a contractor agreement, a school form, a tenancy reference or a delivery note, the first is what is being asked for and what everyone uses. If a counterparty has specifically asked for a certificate-based or qualified signature — some public procurement and some regulated finance does — this page cannot provide it, and you need their process.

Is it binding?

Generally yes. In the UK the Electronic Communications Act 2000 and subsequent case law treat a simple electronic signature as valid; across the EU the eIDAS regulation says an electronic signature cannot be denied legal effect merely for being electronic; in the US the ESIGN Act does the same. What a court looks for is evidence that the person intended to be bound, which is why the surrounding correspondence usually matters more than the mark itself.

The exclusions are narrow and consistent: wills, certain property deeds and transfers, powers of attorney in some jurisdictions, and a few court documents. If you are signing one of those, take advice rather than a web page's word for it — including this one's.

Two details you can see in the result

The drawing is smoothed through the midpoints of the pointer samples rather than joined with straight lines. A pointer reports far fewer positions than a pen leaves ink, so a signature drawn as a polyline comes out faceted — recognisably the work of somebody with an unsteady hand. Curving through the samples fixes it.

And the exported image is trimmed to the ink before it is placed. A signature pad is mostly empty space; if that space were included, setting a width and a position would be sizing and positioning the padding rather than the name inside it, and the signature would land somewhere other than where you clicked.

Afterwards

A signed document is usually one that then gets sent somewhere. Two things worth doing first: check its properties, since the author name and creating application travel with the file, and consider putting a password on it if it is going by email. If the agreement is one you also need to write, the NDA template produces one on the same terms as this — nothing uploaded.

Questions

How do I sign a PDF?

Drop the document in, draw your signature with a finger, stylus or mouse — or type your name and have it rendered in a handwriting face — then click the page where it should go. Download the signed copy. All of it happens in this tab.

Is an electronic signature legally binding?

In the UK and the EU a simple electronic signature is admissible and, for most everyday contracts, binding — eIDAS and the Electronic Communications Act 2000 both say so, and the same is true under the US ESIGN Act. What matters in a dispute is evidence that you intended to sign, not the pixels. A handful of documents are excluded almost everywhere — wills, some property deeds, certain court papers — so check before relying on it for those.

Is this a digital signature?

No, and the distinction is worth understanding. This draws your signature onto the page, which is what almost everybody means and what almost every counterparty expects. A digital signature is a cryptographic certificate embedded in the file that proves the document has not been altered since signing, and it requires a certificate from a trust provider. If somebody has asked specifically for a qualified or certificate-based signature, you need their process, not this page.

Can somebody remove my signature afterwards?

Yes — it is an image drawn onto the page, so anyone with a PDF editor can take it off, exactly as they could with a scanned signed document. That is true of every visible signature. If tamper-evidence is the requirement, a certificate-based signature is the only thing that provides it.

Is my signature uploaded?

No, and this is the page where that matters most on the whole site. A handwritten signature is reusable by anybody holding an image of it. Uploading one to a website — so that it can be stamped onto a contract by a server — hands over the means to sign anything else, in exchange for a job that is a canvas and a little arithmetic. Nothing here is transmitted: open the Network tab and watch while you sign.

Can I sign more than one page?

Yes. Place it on as many pages as you need — initialling every page of a contract is the usual reason — and each placement can be moved or removed before you download.

Will the document still be searchable?

Yes. The signature is drawn as a transparent image on top of the existing page, so nothing underneath is re-rendered: text stays selectable, vectors stay sharp, and images keep their original compression.

What BriskFile will not do to you

  • Your files never leave your device

    Every conversion runs in your browser. Open DevTools, watch the Network tab, and you will see no upload — because there is not one.

  • No account, no email, no watermark

    Nothing to sign up for and nothing stamped on your images. There is no step between choosing a file and getting it back.

  • No limits at the download button

    No daily cap, no file counter, no "upgrade to download". If the tool starts a job, it finishes it.

  • Checkable, not just claimed

    Open the Network tab and convert something — nothing goes out. Or load the page, disconnect, and watch it keep working: the tool is already on your machine, and your file never leaves it.
