How does dynamic sealing work?

Traditional certificate-based seals become static the moment they’re applied.
SealPact’s patented dynamic seal system allows you to:

  • Revoke a seal
  • Supersede an older version
  • Update metadata
  • Correct mistakes

All without altering the original PDF — and with full transparency via the verification page.

Yes. Verification is completely public: all they need to do is scan the QR code or visit the verification link. No login or SealPact account is required. It’s free and frictionless for building departments.
Yes. SealPact-sealed PDFs open normally in Bluebeam, Adobe, Autodesk, and all major PDF viewers — with no installation or add-ons required.

Traditional certificate-based seals (including those used in common PDF tools) are static and cannot be revoked or updated once issued. SealPact uses dynamic sealing, live verification, and AI-driven integrity analysis to provide ongoing post-issuance control for design professionals throughout the document’s lifecycle.
SealPact offers:

  • Live verification
  • Dynamic control
  • Full transparency and audit logs

They represent the old standard. SealPact is the next generation.

You can revoke or supersede a seal instantly. Anyone verifying the document will see:
“This document has been revoked/superseded”
with a timestamp and your updated authoritative status.
