Design your stamp and stamp your drawings right here.
Nothing is uploaded: it all happens in your browser, and you can turn your wifi off halfway through. The app does the same with whole sets.
Design your stamp
Stamp here. No internet.
Up to 10 sheets (PDF pages). Each title block’s number, title and revision are read; you can correct them before stamping.

On a phone, try the sample set. For your own drawings, open this page on a computer and drop them there.
The app stamps whole sets (300+ sheets), with QR codes and a transmittal. Try it free for 14 days.
| # | File | Sheet | Title | Rev |

Each stamp carries a discreet “Stamped at stamppa.com” line underneath; the app does not add it. Here the stamp always goes to the corner you chose. The app also checks every sheet and moves the stamp off the drawing when needed.

How do we know nothing is sent?
This page is served with a security policy (Content-Security-Policy) that says connect-src 'none' and form-action 'none': the browser will not let it make any data request (fetch, XHR, beacon, WebSocket) or post a form. If it ever tried, the counter above would show it.
Check it yourself: open the browser’s tools (F12) on the Network tab, drop your drawings and stamp. No request appears; only the engine loading, which comes from this same site and carries none of your files.
The simplest test: turn your wifi off after the engine has loaded. If anything depended on a server, it would stop working.
Screen-reader users: the stamp and the table work with the keyboard; the result is announced when it is done.
