How to Add a Signature to a PDF
Printing a document, signing it with a pen and scanning it back takes ten minutes and leaves you with a crooked, blurry copy. Adding your signature digitally takes less than a minute and the PDF stays sharp.

Adding a signature to a PDF on your phone or computer
Because everything runs in the browser, the steps are the same on Windows, Mac, Android and iPhone – no app to install. On a phone you simply draw with your finger and move the signature with touch.
Tips for a professional result
- Draw your signature slowly – it looks smoother than fast strokes.
- Make it about as large as a real signature: slightly taller than the text on the line.
- Upload a scan of your real signature for the most authentic look.
- Keep an unsigned copy of the original PDF for your records.
