Everything you need to
seal a drawing
Templates that lock seals to your title blocks, batch placement across whole sets, and a desktop app that works offline.
Built for A/E/S Professionals
Whether you're an architect, engineer, or surveyor, SealKit fits the way your firm already works.
Reusable Templates
Build once, use forever. Create templates for every title block style your firm uses — PE seals, architect stamps, surveyor seals, and more.
Pixel-Perfect Placement
Custom and complex templates lock seals exactly where they need to go — even across PDF sets with multi-size pages and multiple signers.
Batch Placement in Seconds
Place seals on hundreds of pages with one click, then complete signing in seconds. What used to take hours is finished before your coffee cools.
Consistent & Compliant
Every drawing receives the correct seal, signature, license number, and date. Sign directly in the app — no need to open Bluebeam or Acrobat. Prepared documents can also be signed in any PDF handler.
Desktop App
Works fully offline on Windows. Designed to support Responsible Charge and Sole Control requirements under most state sealing laws. Sensitive digital IDs and seal images never leave your machine.
Manage Digital IDs
Easily create self-signed digital IDs or use certificates from most Certificate Authorities (CAs). Manage and apply them across all your templates.
Licensing That Stays Out of Your Way
Try it first, then activate it on the computers you work from.
Free 14-Day Trial
Test the full workflow with up to 2 seals. No credit card required.
Offline Friendly
Your license is checked when you connect. SealKit keeps working for up to 30 days without a connection.
Move Computers Yourself
Deactivate an old machine from the app or your account page, then activate the new one with the same key.
