Part of our Sign PDF Documents Online suite
Signing a PDF online used to mean trusting a cloud service with your document. Every big e-signature platform — DocuSign, Adobe Sign, HelloSign — routes your file through their servers and may keep copies for days or weeks. Here, the file stays in your browser. The drawing pad captures your signature on a local canvas element, the PDF pages render locally with pdfjs, and the final output is stitched together locally with pdf-lib. You get the speed and convenience of an online tool with none of the upload-and-pray. Works on any device with a browser: Mac, Windows, Linux, Chromebook, iPad, or phone.

If you're drawing your signature on a phone, rotate to landscape for more canvas space and a more natural hand movement.
Use the page arrows to flip through the document and confirm which pages actually need your signature before you place it.
Place the signature at the default size first, then drag the corner handle to match the line on the form. Easier than guessing upfront.
