Drop video here or click to upload
Adjust volume from 0% (mute) to 200% (boost)
Video is processed entirely in your browser. Nothing is uploaded to any server.
Instantly remove all audio from your video with a single click.
Increase volume up to 200% for quiet videos.
No library loading required. Start processing immediately.
Use Video Volume when the video itself is fine but the audio level is wrong. If the clip also needs speed changes, continue with Video Speed. If you want the audio as a separate file after correction, continue with Video to Audio.
No-upload workflow: lectures, calls, review clips, and private camera recordings stay on your device while you fix volume.
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.
A common misunderstanding is that turning up the volume slider always makes audio sound louder. In practice, an audio track already near full scale has little headroom, so boosting gain simply clips the peaks and introduces harsh distortion. The right approach depends on what you are fixing: if the audio is simply recorded too quietly with a lot of unused headroom, a gain boost works cleanly. If the audio is already loud and you want it to feel louder, you should instead compress the dynamic range and then normalize, rather than pushing gain into clipping.
If you are assembling several clips, the most noticeable problem is usually inconsistent loudness between them, not a single clip that is too quiet or too loud. The fix is to normalize each clip to a similar overall level so the transitions sound continuous. A common workflow is to listen to the boundaries between segments first and adjust only the clips that stand out, then do a final pass over the whole sequence. This avoids the over-correction that happens when you boost every clip by the same fixed amount.
Changes to volume are best judged by ear on decent speakers or headphones, not by the waveform alone. After you adjust, play the result in a media player rather than the in-page preview, because in-browser preview panes often do not reflect the final file. Check the loudest moments for clipping, then the quietest moments to confirm they are still audible. Export using a standard format, keep the original track untouched until you have confirmed the adjusted version, and back up the source before you replace it.
