Before you get started
Is this a verified digital signature?
No. WaterPDF does not verify identity or issue signing certificates. Check the receiving party’s requirements.
Where is my signature stored?
The app keeps it in this page’s memory only. It is not uploaded or saved as an account profile.
Are my documents uploaded?
No. Selected file contents are processed in your browser. Normal page requests still reach the hosting provider. Use a trusted device and keep your originals.
