Frequently asked questions

Why does the transparent background matter?
It lets the signature overlap existing text and lines without covering them with a white rectangle — so it looks like it was signed on the page.
How do I add it to a PDF?
Download the PNG, then place it onto your PDF in any editor. The whole process stays on your computer.
