Install and update

Windows

Section titled “Windows”

Needs: Windows 10 or 11, 64-bit. No administrator rights: Stamppa installs for your user only.

  1. Download the installer, Stamppa-<version>-setup.exe.
  2. Run it. While Stamppa is new and not yet code-signed, SmartScreen may say “Windows protected your PC”. Click More info, then Run anyway.
  3. Choose the options you want: open PDFs with Stamppa, the right-click menu in File Explorer, start with Windows. You can change them later in Help ▸ Windows integration…
  4. Stamppa opens.

Prefer not to install? The portable .exe runs without installing anything.

Check the file (optional)

Section titled “Check the file (optional)”

Each file’s SHA-256 is on the download page. In PowerShell, in your Downloads folder:

Terminal window
Get-FileHash .\Stamppa-<version>-setup.exe

The two values should match.

Mac

Section titled “Mac”

Needs: macOS 12 or later on Apple Silicon (M1 and newer). Intel Macs: contact us.

  1. Open the .dmg and drag Stamppa to Applications.
  2. The first time, macOS may say it can’t verify the developer.
    • macOS 15 and later: click Done, open System Settings ▸ Privacy & Security, scroll down, click Open Anyway and confirm.
    • macOS 12 to 14: Control-click Stamppa in Applications, choose Open, then Open again.
  3. From then on, Stamppa opens normally.

To check the file: shasum -a 256 ~/Downloads/Stamppa-<version>.dmg

Updating

Section titled “Updating”

When it opens (at most once a day) Stamppa checks whether a new version exists and tells you; you can turn this off. It never downloads anything by itself: it opens the download page. Install the new version over the old one; your license, templates and settings stay.

To stop the daily check, untick Check for updates automatically in the update notice.

Uninstalling

Section titled “Uninstalling”
  • Windows: Settings ▸ Apps ▸ Installed apps ▸ Stamppa ▸ Uninstall. This also removes the right-click menu and the other options. Your settings in %LOCALAPPDATA%\Stamppa are kept in case you reinstall; delete that folder to remove them too.
  • Mac: drag Stamppa from Applications to the Bin.

For IT

Section titled “For IT”

Silent, per-user install:

Stamppa-<version>-setup.exe /VERYSILENT /TASKS="contextmenu,openwith"

Available tasks: desktopicon, contextmenu, openwith, startup. Apart from the daily version check, Stamppa makes no network requests.
