Frequently asked questions
Is a PNG signature legally valid?
An image of your signature is usually fine for informal documents and forms, but whether it is accepted depends on the document and the country. For contracts, check what the other party requires.
How do I use the transparent PNG?
Insert it as a picture in Word, Google Docs or a PDF editor — the transparent background lets it sit on top of the page without a white box.
How can I make a signature from a photo?
Sign with a dark pen on plain white paper, photograph it in good light, upload it with the Upload tab and adjust the ink strength until the lines look clean.
