The easiest way to sign and stamp documents

Use a real pen and paper to create your signature, then apply your signatureit to digital documents — all without leaving your chair.

Stamper has transformed our authorisation workflow - two clicks and every page is digitally stamped! We're saving time, boosting productivity, and protecting the environment.

Say goodbye to printing & scanning

Add text annotations, today's date, and your signature directly to PDFs in the Stamper desktop app for Windows and Mac.

Deliver on your ESG goals

Reducing printer and scanner use doesn't just save you time and money, it also means less paper and electricity go to waste helping contribute to your organisation's ESG aims.

Why Stamper?

Developed to solve the problems of the insurance industry, where underwriters frequently need to apply button stamps and scratches to every page of a document, Stamper now helps people across a wide range of industries.

Underwriters at TMK use Stamper to quickly apply indelible stamps to PDF contracts and treaties, something they weren't able to achieve with tools like Adobe Acrobat.
