Frequently Asked Questions
Is this a legally binding e-signature?
It adds a visible signature image to your PDF, which is fine for many everyday documents. For legally regulated workflows, use a certified e-signature service that provides an audit trail.
What image format should I upload?
A PNG with a transparent background looks best because only your signature shows. JPG works too but will include its background.
