A lightweight Windows tray application that lets you capture the active window with a configurable global keyboard shortcut and automatically saves each screenshot as a high-quality PNG to a folder of your choice.
| Feature | Details |
|---|---|
| Active-window capture | Captures only the currently focused window (falls back to the full primary screen when no window is active). |
| Lossless PNG output | Every screenshot is saved as a 32-bit ARGB PNG — no compression artefacts. |
| Configurable save folder | Choose any folder via the Browse button; the app creates it if it does not exist. |
| Global hotkey | Register any combination of Ctrl / Alt / Shift + a function key or special key. The shortcut works system-wide, even when the app is minimised to the tray. |
| System-tray operation | Runs quietly in the background after you click Start & Minimize to Tray. Double-click the tray icon to reopen the settings window. |
| Single instance | Only one copy of the app can run at a time. |
- Windows 10 or 11
- .NET 10 Runtime (Desktop / WinForms)
- Download the latest release from the Releases page and run
OneClickScreenShot.exe. - Set a save location — click Browse… to pick a folder (defaults to
Pictures\OneClickScreenShot). - Configure the hotkey — check one or more modifier keys (Ctrl / Alt / Shift) and choose a key from the dropdown. The default is Ctrl + PrintScreen.
- Click Start & Minimize to Tray — the app registers the hotkey and hides to the system tray.
- Focus the window you want to capture and press your hotkey. A balloon notification confirms each saved file.
