PDF Signer: Instantly add, save, and precisely place handwritten signatures on PDFs—securely and free.
PDF Signer is a free, browser-based tool that lets you add handwritten signatures to PDF documents in seconds—without installing any software. Simply draw your signature using a mouse, trackpad, or touchscreen, and the tool instantly turns your strokes into a signature that can be placed neatly on the document. You can save unlimited signatures to a personal library, so repeated signers (or different signature styles for different purposes) are always ready when you need them.
To make placement effortless and accurate, PDF Signer supports precise drag-and-drop positioning with real-time preview. That means you can see exactly where your signature will appear before finalizing, helping you avoid misalignment on forms, contracts, or application documents. The workflow also supports multi-page signing, allowing you to apply signatures across one or many pages in a single session.
When you’re done, you can download the signed PDF instantly. The signatures are embedded directly into the PDF file, so the layout and appearance remain consistent when shared or printed. For privacy, PDF Signer performs 100% of the processing on the client side in your browser—no uploads, no registration, and no watermarks. This makes it a fast and secure option for everyday signing tasks such as leases, consent forms, invoices, and legal paperwork.
