Download

Grab the latest Windows build from the Releases page. Unzip and run ZyveroImageOptimizer.exe — no installation required.

Trial & licensing

The app runs fully featured for a 10-day free trial on first launch (no account needed). After the trial, activate with a license key purchased from Gumroad — see the "🔑 License" button in the app, or the product page.

Auto-updates

On launch, and any time you click ⬆ Updates in the app, it checks this repository's latest release via the GitHub API and lets you know if a newer version is available. It never downloads or installs anything automatically — it opens the release page (or a direct asset link, if attached) for you to grab manually.

See updater.py for the implementation and RELEASING.md for how to cut a new version that the updater will pick up.

Building from source

Requires Python 3.11+.

pip install -r requirements.txt
python main.py

To build the standalone Windows executable:

pip install -r requirements-dev.txt
pyinstaller pyinstaller.spec --noconfirm

The build lands in dist\ZyveroImageOptimizer\. See WINDOWS_INSTALLER_BUILD.md and scripts/build_all.md for installer/MSIX packaging and for Linux/macOS builds.

Note: pyinstaller.spec references an optional assets/Zyvero.ico app icon. It isn't included in this repo yet — add your own icon there, or the build will proceed without a custom icon.
