No. Sign PDF Document runs entirely in your web browser on Windows, Mac, Linux, iOS, and Android, and never stamps watermarks onto your exported documents or images.

Standard free usage supports generous daily operations up to 10MB per upload with zero sign-up required. Upgrading to ProIT Pro or Business unlocks up to 100MB+ file sizes, bulk batch ZIP processing, and headless API key access.
