1. Open your file
Choose the PDF and go to the page that needs the mark. Keep an unsigned source copy before adding signatures or other content.
2. Work through the settings
- Use Create signature and choose Draw, Type or Upload. Check the preview before using the signature.
- Move the mark to the signature area and resize it so it fits the line. Arrow keys can help with small position changes.

Questions you may have
Is this the same as a certificate-based digital signature?
No. It adds a visible mark to the page. A certificate signature has a different cryptographic verification process.
Can I use my own signature image?
Yes. Upload a supported image you are authorized to use, then check its size, background and placement.
