Why use ZillaKit's Sign PDF tool?
This is a free online PDF signer that asks for no signup and no email, and — this matters most with signatures — your PDF never leaves your device. Every step, from rendering the pages to stamping your signature into the file, runs inside your browser using pdf.js to preview and pdf-lib to write the final document. Nothing is uploaded to a server, so contracts, consent forms, tax paperwork, and anything else confidential stay entirely private. You can draw a smooth signature with your finger on a phone or tablet, or with a mouse on a laptop, and adjust the pen thickness and ink colour. Prefer to type? Enter your name and it becomes a clean cursive signature. Place signatures, dates, and text on any page, drag them exactly where they belong, and resize with a handle. When you download, everything is flattened into the PDF so it looks the same everywhere. It works on phones, keeps working offline once loaded, and includes generous free daily use with no watermark on your signed file.
FAQ
Is my PDF uploaded to sign it?
No. The whole process happens locally in your browser. Your document and your signature never leave your device and nothing is sent to a server — which is exactly what you want when signing sensitive paperwork.
Can I sign a PDF on my phone?
Yes. The signature pad works with touch, so you can draw your signature with a finger or stylus, then drag it into place. The preview is responsive and scrolls on small screens.
Do I need to create an account or pay?
No signup and no email are required, and there is no watermark on your signed PDF. Free daily use is generous; heavier users can go Premium for unlimited runs.
Is a drawn or typed signature legally valid?
In many places an electronic signature you apply with intent to sign is legally recognised, but rules vary by country and document type. For important agreements, check the requirements that apply to you or use a qualified e-signature provider.
Can I add the date and initials too?
Yes. Besides signatures you can drop a date field or any custom text onto any page, then move and resize it just like a signature.
