How It Works

Set it up once in seconds, then control your active window audio effortlessly.

1

Select a convenient hotkey

Choose any key combination that feels natural to you. QuickMute checks for key conflicts automatically and lets you rebind it anytime.

2

Select a working mode

Pick 2-step (mute ↔ unmute) or 3-step (lower volume → mute → unmute) depending on how you prefer to handle audio.

3

Adjust optional settings

Configure your preferred quieter volume level (e.g. 10%), on-screen indicator duration, or protect specific applications with process exclusions.

4

Close the app

Close the settings window when done. QuickMute runs silently in the background in your system tray and starts automatically with Windows.

5

Press your hotkey anytime

Press your hotkey to instantly mute the currently active window. Press again to unmute.

Why QuickMute

Straightforward, single-purpose utility designed to do one thing reliably.

Mutes only your active app

Targets whichever window you are actively using. Your background Discord call, music, or other apps remain unaffected.

Quieter volume mode

Step down volume to 10% instead of total silence when you just need to lower background noise to hear someone talking.

Discreet on-screen indicator

A small floating toast in the corner confirms the volume status, then fades. It never steals keyboard focus or interrupts full-screen games.

Customizable shortcut

Change your global shortcut anytime in settings, with automatic detection if another app is already using the combination.

System safeguards

Core Windows processes like Explorer and Task Manager are automatically protected so you don't accidentally silence essential system audio.

Native & lightweight

Built in native C# with .NET 8 WPF. Starts instantly, runs quietly in the system tray, and consumes minimal system resources.

Verify Download

You can verify the installer checksum in Windows PowerShell prior to running it.
