Frequently asked questions
Is a drawn signature legally binding?
That depends on your country and the document. This tool places a picture of a signature on the file. It does not add a government digital certificate.
Can other people copy my signature from the PDF?
Yes, just as they could from a paper scan. Only sign files you trust, and do not reuse a signature image carelessly.
Is the PDF uploaded?
No. Signing and watermarking happen on your device.
Will the watermark cover the text?
It sits on top with some see-through so the words underneath stay readable. You can change how solid it looks with the slider.
