Ratifio vs Nitro Sign

Nitro built a PDF editor, then added signatures. Ratifio built signing, then made it auditable.

Nitro is a PDF productivity platform that added e-signatures (Nitro Sign) to compete with Adobe. It's a capable tool for teams that need PDF editing and signing together. But when compliance is your primary concern — audit trails, tamper evidence, regulatory documentation — you need a tool that was designed for scrutiny, not for PDF editing.

Why teams switch from Nitro Sign

Chain of custody, end to end

Every action is logged with IP address, user agent, ISO 8601 timestamp, and document hash. Consent text recorded verbatim. Not a summary — the actual evidence trail your regulator expects.

7-year retention, standard

Financial regulators expect 7 years. Healthcare expects 8-10. Ratifio stores documents and audit trails for the full retention period with immutable logs and automated retention management.

Tamper-proof by design

SHA-256 hash at upload, recorded before signing begins. Any modification to the document after upload is cryptographically detectable. This isn't a feature — it's the architecture.

Your infrastructure, your rules

REST API, webhooks, bulk operations, and white-label embedding. Ratifio fits into your existing compliance stack. Integrate with your GRC platform, case management system, or internal workflow.

The bottom line

Nitro is a solid PDF productivity tool that happens to include signing. Ratifio is a compliance signing platform that happens to handle PDFs. If your regulator cares about how documents were signed, that distinction determines which tool you need.
