A form lands in your inbox and needs a signature by this afternoon. You do not need a printer or an app. Your phone's browser is enough, and the document never has to leave your phone.

Tips for a signature that looks right

- Draw slowly and use the full width of the pad.
- If it looks wobbly, press Clear and try again.
- Zoom the page with the browser before dragging, if the line is tiny.
Is it valid?
Adding an image of your signature is accepted for many everyday documents, such as forms and permission slips. Some contracts and authorities need a certified digital signature or a particular service, and the rules differ by country. If in doubt, ask the person who sent the document. This is not legal advice.
Your signature stays private
The signature is drawn and stored only in your browser while the page is open. It is not uploaded or saved, so you will draw it again next time.
