Download the desktop app (Windows)

The desktop version of the AoH2 Save Editor is a free, standalone Windows program. It does everything the web editor does, and is a better fit if you edit saves often or work with very large save files.

Desktop vs. web — which should I use?

• Desktop app: runs offline, no ads inside the program, handles huge saves a bit faster. Windows only.
• Web editor: nothing to install, works on any device including phones and Linux/Mac, always the latest version. Your saves stay in your browser — nothing is uploaded.

How to install

1. Click the download button above and grab AoH2SaveEditor.exe.
2. Double-click it to run — no installer, single portable program.
3. Windows SmartScreen may warn about an unrecognized app. Choose More info → Run anyway, or build from source — the full code is public on GitHub.

Requirements

• Windows 10 or 11.
• Nothing else — the .exe is self-contained.

Safety

The editor never overwrites your original saves — it writes edited copies and keeps timestamped backups in a separate folder. The project is open source, so you can inspect exactly what it does.
