Adjust video volume online free with FreeToolBox — increase, decrease, or mute the audio track of any video file right in your browser. Sometimes videos are recorded too quietly or too loudly. Our Video Volume Adjuster uses FFmpeg.wasm to modify the audio gain without re-encoding the video stream, boosting quiet recordings, lowering overpowering audio, or completely muting a video (useful for creating silent social media clips).
All adjustments run locally in your browser using WebAssembly — your video never leaves your device. The output has no watermarks. Completely free, no account required.
You can increase volume by up to 400% (4×). However, pushing too high causes clipping (audio distortion). Consider using the normalize option to automatically bring audio to a consistent level without clipping.
Audio normalization analyzes the loudest peak in your video's audio and adjusts overall volume so that peak reaches a target level (typically -1 dBFS). This brings quiet videos to a standard listening level without distortion.
Yes. The mute option removes the audio track entirely. This is faster than adjusting volume since no audio re-encoding is needed — the audio stream is simply dropped.
No. FFmpeg.wasm handles all audio processing locally in your browser. Your video file never leaves your device.
