Good to know
Your signature is drawn on a canvas, saved as a transparent image and placed on the page you choose. Pages that were rotated in the original may place it differently, so check the result.
Privacy: where the work happens
Your file is read by your browser and processed by JavaScript on this page. The result is created on your device and offered as a download. Only the page code, and any library this tool needs, is downloaded from cdnjs or jsDelivr.
Questions
Is this a legally binding digital signature?
It places an image of your signature on the page, like signing on paper. It adds no cryptographic certificate, so check whether the receiver needs one.
Can I move the signature afterwards?
Not in this tool. Choose another position and run again from your original file.
