About This Tool

Utilitly's Sign PDF tool adds an electronic signature to any PDF — 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 applies an electronic visual signature (e-signature), which is legally accepted for most common business and personal agreements — contracts, invoices, forms, and letters. It's important to be precise, though: it does not apply a cryptographically certified digital certificate with an audit trail. For agreements that specifically require certified digital signatures, use a dedicated certificate-based service. For everyday signing, an e-signature like this is widely accepted.
