Questions
Is my PDF uploaded?
No. This tool runs in your web browser, so the file stays on your device.
Is this a legally binding digital signature?
Swoopty adds a picture of your signature. It is not a cryptographic digital signature and does not prove who signed or detect later changes. Check what the recipient accepts.
