faq

Practical boundaries before you process a file.

Is this a legal digital certificate signature?

No. This MVP adds a visible typed signature mark. Certificate-based signing is a separate advanced feature.

Does the signed PDF upload anywhere?

No. The visible signature is added locally in the browser and downloaded as a new file.
