How to sign a PDF electronically
Updated June 21, 2026
Printing a document just to sign it and scan it back is slow and wasteful. For most agreements, a clear electronic signature placed on the PDF is accepted and far quicker.
This guide explains the simple way to sign a PDF and where each method fits.
Three ways to create a signature
You can draw your signature with a mouse or finger, type your name in a handwriting-style font, or upload a photo of your real signature on white paper. Drawing on a touchscreen gives the most natural result; uploading a scan of your real signature looks the most authentic.
Place it where it belongs
Drag the signature to the signature line and resize it so it sits naturally. You can also add the date next to it as a small text note. Keep it large enough to read but in proportion with the surrounding text.
Sign privately and for free
Contracts are exactly the kind of document you should not upload to a random website. Our Sign PDF tool keeps everything in your browser, so the document and your signature never leave your device. There is no watermark and no account needed.
Step by step
- Open the PDF. Drop your document into the Sign PDF tool.
- Create your signature. Draw, type or upload your signature.
- Place and download. Position the signature, then download the signed PDF.
