FAQ

Does this add a legal digital signature?

No — it stamps an image of your signature onto the page (visual only). For a certified digital signature, use a dedicated e-sign tool.

What image format should I use?

PNG (ideally with a transparent background) or JPG both work.

Where is the signature placed?

On the last page, at the bottom — you can choose left, center, or right.
