Secure signing covers the last mile before a PDF leaves your org: signatures, encryption, watermarks, and optional trackable delivery.

Running a tool on a single file costs nothing. You pay when you want the platform to hold onto things for you — workspace folders, team seats, and the analytics behind published forms and share links.

It travels over an encrypted connection, the tool does its job, and the upload is discarded once the task finishes. Nothing sticks around unless you deliberately save the result to a workspace folder.

DSNOOPDOC captures drawn or typed signatures directly on the PDF, which is sufficient for most routine agreements. For regulated industries or high-stakes contracts, confirm the e-signature requirements in your jurisdiction first.

Yes — the two layer together. Encrypt or watermark the file first, then send it through a trackable link so you get both access control and proof of delivery.
