Make the image look natural
- Use a sharp photo with dark ink and even light.
- Crop around the full signature, including long first or last strokes.
- Keep signature images private; the visible handwriting can be copied like any other image.
Questions
Can I use a signature image already in Photos?
Yes. Load it while creating a signature and use the same paper-cleanup controls as a camera scan.
Why does a white box appear around some signatures?
The paper is still part of the image. Clean the background before placing the signature so the PDF shows only the ink.
