Questions, answered
Is this a legally binding digital signature?
It places a picture of your signature on the page, the same as signing a printout and scanning it, which many everyday forms and agreements accept. It is not a certificate-based digital signature, so it doesn't prove who signed or lock the file against changes.
Is my signature saved?
No. Your signature exists only in this browser tab and is gone when you close it. Nothing is uploaded.
Are my files uploaded anywhere?
No. This tool runs entirely in your browser, so your file never leaves your device. You can even run it once, disconnect from the internet, and run it again: it still works, because the processing code is already on your device.
