About This Tool

Utilitly's Sign PDF tool adds your signature to any PDF as an image — a contract, an invoice, a consent form, or a personal letter. Instead of the print-sign-scan routine, you sign on screen and download a finished document, with everything handled in your browser so sensitive files stay private.

Draw or upload your signature

Create a signature whichever way suits you: draw it directly on screen for a natural handwritten look, or upload a pre-saved image of your signature to reuse it consistently across documents.

Place multiple signatures, on any page

You're not limited to one. Draw or upload as many signatures as you need and place them on different pages before applying — useful for documents that need initials on several pages or signatures from more than one spot.

Sign privately — your document never leaves your device

There's no upload and no server copy. The Sign PDF tool runs completely locally in your browser, so your private documents and signatures are never transmitted over the internet. If you've searched for how to sign a PDF without uploading it, this gives you that peace of mind by design.

Is an electronic signature legally valid?

This tool places your signature on the page as an image — the same thing you get from printing, signing, and scanning. To be precise about the limits: it does not apply a certificate-based digital signature, a timestamp, tamper-evidence, or an audit trail. Whether an image signature is enough depends on the agreement and your jurisdiction; where a certified digital signature is required, use a dedicated certificate-based service.

Frequently Asked Questions

Is my signed document uploaded to your servers?

No. The Sign PDF tool runs completely locally in your browser. Your documents and signatures are never transmitted over the internet, so sensitive files stay entirely on your device.

How do I add my signature to a PDF?

Add your PDF, then either draw your signature on screen or upload a saved image of it. Position it on the page, apply, and download the signed document.

Can I place multiple signatures?

Yes. Draw or upload as many signatures as you need and place them on various pages before clicking Apply.

Is this a legally binding digital signature?

No. It places your signature on the page as an image, the same as a scanned signature would be. It does not apply a certificate-based digital signature, a timestamp, or tamper-evidence — for agreements that require those, use a dedicated certificate-based service.

Can I upload an image of my existing signature?

Do I need to print and scan anything?

No. The whole point is to skip printing and scanning — you sign on screen and download a finished PDF.
