Everything you need to sign PDFs online

Already have a scanned signature? Upload a PNG or JPG — transparent backgrounds are fully supported.

About This Tool

The easiest way to sign PDF files online — for free

Whether you need to sign a contract, approve a form, authorise a document, or add a personal touch to any PDF, Webzio's free online PDF signer makes it effortless. No software to download, no subscription to start, and no file ever leaves your device.

Unlike traditional e-signature platforms that require account creation and charge monthly fees, our tool is completely free and runs 100% inside your web browser. We use PDF.js to render your document with high fidelity and pdf-lib to embed your signature directly into the PDF at publication quality — meaning the signature becomes a genuine part of the file, not a floating overlay.

Our PDF signing tool is ideal for freelancers, small businesses, students, legal professionals, and anyone who regularly handles paperwork. Sign NDAs, employment contracts, rental agreements, invoices, permission slips, and more — all without printing a single page. It works on Windows, Mac, iOS, and Android — any modern browser is all you need.
