SignFile allows users to upload, sign, and send documents like contracts and NDAs with no account required for signers, and provides a verification link instead of a login.
The process involves three simple steps: drop a PDF (which is sanitized to remove hidden JavaScript), add signers and signature fields, then sign and send with a real-time audit trail.
Every completed document receives a public verification link showing who signed, when, and a SHA-256 fingerprint that detects any changes.
SignFile offers four pricing tiers: Free (3 documents/month), Starter ($9/mo, 30 documents), Pro ($19/mo, unlimited documents), and Team ($29/mo for 5 seats plus $5/seat extra).
All plans include SHA-256 tamper-proof documents, full audit trail, ESIGN Act compliance, and public verification pages.
Key security features include encryption (TLS 1.3), sanitized PDFs, one-time signing tokens, and SHA-256 tamper protection for legal validity.
SignFile is month-to-month with no long-term contracts, and signed documents remain accessible with read-only access even after cancellation.
