Connection Keeper — Keep Your Audio Devices Always Connected
The free browser tool that prevents Bluetooth speakers, car audio, and headphones from disconnecting due to inactivity.
Bluetooth speakers, car audio systems, and wireless headphones often disconnect after a few minutes of silence. This is frustrating when you're working, meditating, or just enjoying quiet time. Connection Keeper plays an inaudible or ultra-quiet signal that tricks your audio device into staying connected — all from your browser, no app installation needed.
Features
- Multiple Signal Types — Choose from silent tone (1 Hz), micro-pulses, pink noise, brown noise, or a custom frequency. Each type is optimized for different devices and scenarios.
- 6 Ready-Made Presets — Quick-start scenarios for Bluetooth speakers, car audio, sleep, hearing aids, HDMI receivers, and work focus. One click to start.
- Background Playback — Advanced keep-alive technology ensures the signal continues even when you switch tabs, lock your phone, or turn off the screen.
- Screen Wake Lock — Optional feature to keep your screen on — useful for presentations, dashboards, or when you need the display active.

How to Use Connection Keeper
- Open Connection Keeper in your browser on any device — phone, tablet, or computer.
- Choose a preset that matches your scenario (Bluetooth Speaker, Car Audio, Sleep, etc.) or customize the signal type manually.
- Click "Start Keep-Alive" — the tool will begin playing an inaudible signal to keep your audio device connected.

Frequently Asked Questions
Why does my Bluetooth speaker keep disconnecting?
Most Bluetooth speakers have a power-saving feature that automatically disconnects after 10-15 minutes of silence. Connection Keeper prevents this by playing an inaudible signal that keeps the audio stream active.
Will I hear the keep-alive signal?
No. The default "Silent Tone" mode uses a 1 Hz frequency that is far below human hearing range. Other modes like pink or brown noise can be set to extremely low volume levels that are effectively inaudible.
Does it work in the background on phones?
Yes. Connection Keeper uses advanced browser APIs (Media Session, Web Locks) to keep running even when you switch apps or lock your phone. For best results on iOS, keep the browser tab active.
Will it drain my battery?
Connection Keeper is designed for minimal CPU usage. The silent tone mode uses almost no processing power. For sessions longer than 2 hours, we recommend plugging in your device.
Can I use it with my car audio system?
Absolutely. The "Car Audio" preset is specifically designed for car Bluetooth systems that disconnect when there's no audio playing. Just start it before your drive.
Does it work with HDMI and wired connections?
Yes. While the tool is optimized for Bluetooth, it works with any audio output. HDMI receivers and soundbars often have similar timeout behavior that Connection Keeper can prevent.
Can I download the keep-alive signal as a file?
Yes. Use the "Download Keep-Alive File" section to generate an MP3 or WAV file with the signal. You can then play it on repeat from any music player, even without internet access.
Is it really free?
Yes, Connection Keeper is completely free with no registration, no ads, and no limits. All processing happens in your browser — your audio data never leaves your device.
