Quick answer

Open PDF Sign in Chrome, draw your signature, choose the PDF, place the signature and download the signed file.

Step by step

  1. Open Chrome and go to PDF Sign.
  2. Draw your signature with your finger or a stylus, pick an ink color and tap "Use this signature".
  3. Tap the drop area and pick the PDF from Recent, Downloads or Google Drive in the file picker.
  4. Tap the page to place the signature, drag it onto the signature line and resize it with the corner dots.
  5. Tap "Save signed PDF". Tap the Chrome download notification to open the file, or find it in the Downloads section of your Files app.

Tips

  • A stylus gives the most natural signature on a tablet or a phone that supports one.
  • Rotate the phone to landscape for a bigger pad and page preview.
  • Keep the unsigned original so you can compare or redo it.

Good to know

This is a drawn signature image and not a certificate-based digital signature, so check what the other party accepts. Your PDF stays on your phone and is not uploaded.
