At home on macOS
Built into the Mac, not ported to it
The same Stamppa as on Windows, wired into what makes a Mac a Mac.
Finder Quick Actions
Right-click files in the Finder, then Quick Actions. Stamppa adds these on its first start; Help ▸ Finder integration… switches them off any time.
OCR with Apple Vision
Scanned sheets become searchable with macOS’s own text recognition. Nothing extra to install.
The Mac menu bar
File, Edit, View, Pages, Review, Measure, Tools, Window and Help live in the system menu bar, organized by workflow.
Quick Look
Signatures and stamps added in Stamppa look right in Quick Look, before you even open the file.
Printing to each sheet’s paper
“Match each drawing” prints every sheet on its own paper size, and whole sets print in sheet order.
Dark mode
A dark interface, plus an optional dark paper on screen only. Your files stay as they are.
Your default PDF app
Set Stamppa as the default for PDFs. However many files you open, they land in one app, in tabs.
Mac and Windows
One app on both, not a lighter Mac edition
Same features
One codebase since version 4: every tool on Windows is on the Mac, and the full test suite runs on both.
Same files
Standard PDFs and markups, so a set marked up on a Mac opens on a colleague’s PC as it is.
Same license
Each person can use Stamppa on up to 3 computers, Mac or Windows.
What it costs
The same price on Mac and Windows
Pay once a year and Stamppa 27 is yours forever, with every 27.x update, including the ones released after you cancel. It renews at your same price. There is a monthly plan too: after 12 months paid in a row, that day’s version is yours.

Questions from Mac users
Ask Gus anything elseDoes Stamppa run natively on Apple Silicon?
Yes. macOS 12 or later on Apple Silicon (M1 and newer). It does not run on Macs with Intel processors.
Is the Mac version the same as the Windows one?
Yes. Stamppa has one codebase for Windows and macOS, with the same tools, the same files and the same license: each person can use it on up to 3 computers, Mac or Windows.
Can I still use Bluebeam Revu on a Mac?
Not as a Mac app. Bluebeam set the end of life of Revu for Mac on June 28, 2023, and points Mac users to Bluebeam on the web and mobile, or to Revu for Windows on a Mac through Boot Camp or Parallels. Stamppa runs natively on Macs with Apple Silicon and opens your Revu PDFs with their markups.
What can I do from the Finder?
Right-click files and choose Quick Actions: Open in Stamppa, Convert to PDF (for Word, Excel and PowerPoint files), Convert PDF to Office, Print with Stamppa (sheets in order) and Run a Stamppa action (chained batch actions on PDFs or folders). Help ▸ Finder integration… turns them off.
Will macOS let me open it?
Yes. Stamppa is signed for macOS, so it opens like any other app.
