Sign PDF
First, let’s save your signature. You only do this once.
- Sign on plain white paper with a dark pen.
- Take a photo of it, close up and straight on, in good light.
- I’ll clean it up and turn it dark blue.
Signatures stay on this phone. They are never uploaded.
Cleaning up the photo…
Sign across the box with your finger. Use the whole width.
Is this your signature?
It will be see-through, so it sits on your PDF like real ink. Use the slider if the lines look broken or too heavy.
