In today’s digital-first engineering workflow, paper is no longer the only medium that needs an official seal. Drawings, reports, calculations, and submittals are routinely shared as PDFs, transmitted through project management platforms, and stored in electronic archives. A traditional rubber stamp simply can’t keep up. That’s why the Professional Engineer eSeal—also called an electronic image stamp of seal—has become an essential tool for licensed engineers.
What Is a Professional Engineer eSeal?
A Professional Engineer eSeal is a digital version of the traditional engineer’s seal. It is a high-resolution electronic image (usually a PNG or PDF overlay) that contains the same required elements as a physical seal:
Engineer’s full name
License or registration number
State or jurisdiction of licensure
The words “Professional Engineer,” “P.E.,” or the equivalent title
Official seal design or emblem (when required by the licensing board)
The eSeal is applied electronically to digital documents, producing a clean, consistent, and professional mark that travels with the file.
