Sign PDFs online, in seconds

Draw your signature with the mouse or stylus, type in a signature font, or upload a signature PNG. Place it on any page.

Signing PDFs is the most common one-off PDF task. The Rankato Sign tool gives you three ways to create a signature — draw with the mouse or stylus, type using a signature-style font, or upload a scan of your handwritten signature. Position on any page, resize freely, and download. Purely visual signature; for cryptographically-signed PDFs, use Adobe or a dedicated signing service.

Three signature modes

Draw: sign with the mouse, trackpad, or stylus on a signature canvas. Type: enter your name in one of several signature-style fonts. Upload: drop a PNG of your handwritten signature (transparent background works best).

Placement

After creating the signature, drop it anywhere on any page. Resize by dragging corners. Add a date field automatically, or type additional text near the signature. Multiple signatures on one document if you need initials + full signature.

Visual vs. cryptographic signatures

This tool creates a visual signature — the mark appears on the page but doesn't cryptographically bind the document. For legally-binding e-signatures with audit trails and certificate-based signing, use DocuSign, Adobe Sign, or a similar service. For everyday contract signing (leases, agreements between individuals), a visual signature is usually accepted.

Tool FAQs

Everything you need to know about using Sign PDF.

Does my PDF get uploaded to a server?+

No. This tool runs entirely in your browser using pdf-lib and pdf.js loaded as WebAssembly. Open your browser's Network tab while processing and you'll see zero uploads — your PDFs never leave your device. That's why confidential contracts, tax records, and internal docs are safe to run through this tool.

Are signed PDFs legally binding?+

Varies by jurisdiction and document type. In many contexts (US ESIGN Act, EU eIDAS Simple Electronic Signatures) a visual signature counts, but high-stakes contracts often require certified digital signatures. Check with your legal counsel for your specific situation.

Can I process multiple PDFs at once?+

Yes — batch mode is available on the Pro plan. Free users process one file at a time. Pro unlocks unlimited concurrent PDF processing across every tool in the suite.
