Sign PDF
Add your signature to any PDF document. Draw a signature with your mouse or finger, type your name in a handwritten style, or upload an image of your signature. Then click the page to place it, drag it into position, and download the signed PDF.
How to Use
- Upload the PDF you need to sign.
- Create your signature: draw it, type your name, or upload a signature image.
- Click anywhere on the page to place the signature.
- Drag the signature to move it, or use the corner handle to resize it.
- Switch pages and place signatures on as many pages as you need.
- Click Sign PDF to embed the signatures and download the signed document.
How It Works
Your signature is captured as a transparent PNG image. Each placement is stored as a position relative to the page size, so it maps precisely onto the PDF's coordinate system. pdf-lib embeds the image into each page at the chosen position, then saves the finished document. Nothing is uploaded to a server — all processing happens in your browser.
