Overview
What is an electronic seal on a PDF?
An electronic seal (eSeal) is a high-resolution image of your state-licensed professional stamp — typically delivered at 300 DPI in TIF, JPEG, or PNG format. Whether you are an engineer, architect, surveyor, notary, geologist, forester, appraiser, or another regulated professional, suppliers often include digital files with physical stamp orders so you can work on PDFs right away.
StampDocs is the placement layer: upload your seal file, open your PDF, click where the seal belongs, adjust diameter and rotation, and export a stamped document — without printing, scanning, or desktop software.

Verify state board requirements before filing
