Sign a PDF online for free
This free signature and eSign tool lets you create a handwritten-style signature and place it on a PDF, entirely inside your browser. Draw your signature with a mouse or finger, or type your name and pick a cursive style. The tool turns it into a transparent PNG you can download or drop straight onto your document. Then load a PDF, drag the signature to the right spot, resize it, choose the page, and download a signed PDF.
Everything runs locally with JavaScript, so neither your signature nor your document is ever uploaded to a server. That keeps contracts, forms, and agreements private. The signature is embedded into the chosen page at full quality. Works on desktop and mobile and runs offline once loaded.
How to sign a PDF
Create your signature by drawing or typing, press Use this signature, load your PDF, drag the signature where it belongs and resize it with the corner handle, move to the correct page, then press Apply signature and Download.

Does it work on my phone?
Yes. You can draw with your finger, and dragging and resizing work with touch on iPhone and Android.
