Hatch E-Stamp Studio is a browser-based home for everything related to stamping documents: designing your own custom stamp, signing on the dotted line, and sealing a PDF so it's ready to send.
No printer, no ink pad, no scanner queue. Just a webpage that lets you design a stamp once and use it again and again.
Think of it as a digital stamp pad that lives in your browser. You build a stamp that looks and feels like the real thing, save it to your own library, and then click it straight onto any PDF that needs your seal of approval. Add a signature on top, a date that updates itself, even a handwritten note, and you're done.
Whether you're working solo or running a whole department, there's a setup that fits.
One reliable stamp for invoices, certificates, and contracts. Quick, simple, done.
A shared stamp library so everyone on the team is using the same approved seal.
Multiple stamps, many users, and an admin dashboard to keep it all under control.
The five things people open the app for, day to day.
Pick a shape, a colour, a border style, then add curved text, a logo, a date, or little decorative flourishes. It's basically a tiny design studio just for stamps.
Every stamp you make gets saved so it's ready whenever you need it. You can also export a stamp to share it, or import one someone sent you.
Upload a document, click where you want your stamp to land, and adjust the size, angle, or transparency until it feels right. Works across multiple pages, no problem.
Snap a photo of your signature or upload a scan. The background gets cleaned up automatically so it sits naturally on the page.
When a document is finished, lock it in. Everything gets flattened into the page itself and a tamper-evident fingerprint is tucked into the file.
Six simple beats, from first login to final download.
Answer a few quick questions and the platform suggests a plan that fits how you'll use it.
First time only. Design something that looks like you, then save it for later.
Drag it in or browse for it. It opens right there in the document view.
Click wherever it belongs. Add a signature or a bit of text too, if needed.
Nudge the size, rotation, or opacity until everything sits just right.
Export the finished PDF, sealed if you'd like, ready to send off.
Every plan includes unlimited stamping, plus the ability to import and export stamps.
Join thousands of professionals who've left the ink pad behind.
What this does:
What this does not do:
This is a meaningful deterrent and tamper-evidence layer, not an unbreakable lock. No software, including ours, can make a digital file truly impossible to edit.
Upload a PDF, pick a stamp from the library, then click to place it.
Click a stamp to use it on documents. Only custom-built stamps appear here (no built-ins).
Stamp smarter. Scale confidently. Every plan includes our core stamp builder and PDF stamping engine.

They'll be created under your organisation with a temporary password.

Select a .estamp file to submit it for review — no access code needed, every submission (built or imported) goes through the same review process.
Upload proof that this stamp belongs to you — a photo of the physical stamp, a registration certificate, or both. A platform reviewer will approve it before it becomes usable.
