Good to know
- Visual preview only. It does not verify identity, record a signing process, notarise or issue a digital-signature certificate.
- Do not use it to execute agreements or authenticate documents.
- Placement works correctly on rotated pages too.
- Free account required — no card, no trial, no watermarks added by us.
