Sign without a printer

Place your signature on the page and download the signed document.

No print, sign, scan

The whole loop of printing a document, signing it by hand and scanning it back disappears. The signature is placed on the page directly.

Put it where it belongs

Position the signature on the right page and the right line rather than accepting wherever a tool decides to drop it.

Reusable

Once your signature exists you can apply it to the next document without recreating it each time.

Sign a PDF that was sent to you

Contracts, consent forms, tenancy agreements and delivery notes arrive as PDFs and are expected back signed. The print-sign-scan loop needs a printer, a scanner and a flat surface, and produces a crooked grey image of a document that was perfectly clean when it arrived.

Signing directly keeps the document clean and takes a fraction of the time. The signed file is a PDF like the one you received.

No printing or scanning: place the signature on the page exactly where you want

Where a drawn signature stands, and where it does not

A signature image placed on a document is what most everyday agreements ask for, and it is what the print-and-scan route produces too - a picture of a signature on a page.

It is not a cryptographic digital signature, which is a different mechanism that proves who signed and that the file has not changed since. If a counterparty has asked specifically for a digitally signed or certificate-based PDF, that is not what this produces.

Sign a PDF in the browser

Nothing to install, which matters most on a phone - drawing a signature with a finger on a touchscreen is usually easier than with a mouse.

Upload from your device, from a link or from cloud storage, up to 50 MB without an account.

Security you can check

A page about protecting a document has to be clear about how the document itself is protected here.

TLS with modern ciphers

The upload, the processing and the download all run over an encrypted connection, and personal data is stored encrypted.

No human access at any point

Nobody reads your file, looks into it, or makes a copy. The whole pipeline is automated and no backup of a user file is kept.

GDPR, and your rights intact

Processing follows the GDPR. You keep the copyright, and nothing is fed into AI training.

Frequently asked questions about signing PDFs

Is it free to sign a PDF?

Yes. Sign PDF is free and needs no account. Files up to 50 MB can be signed without registering, and a free account or a paid plan raises that limit.

Is a signature added this way legally valid?

For most everyday agreements a signature image on the page is what is expected, and it is the same thing print-and-scan produces. Where a specific form of electronic signature is required by law or by contract, check what has been asked for.

Is this a digital signature with a certificate?

No. This places your signature on the page. A certificate-based digital signature is a different mechanism that also proves the file has not changed since signing.

Can I sign a PDF on my phone?

Yes, and it is often easier - drawing a signature with a finger on a touchscreen beats doing it with a mouse.

Can I put the signature where I want it?

Yes. Position it on the page and the line it belongs on before applying.

Is it safe to sign a document online?

Yes. Every transfer runs over TLS with modern ciphers and personal data is stored encrypted. Nobody reads your file or makes a copy of it, no backup of a user file is kept, and your copyright is untouched. Processing follows the GDPR.
