Change Video Volume

What Does the Change Video Volume Do?

The Change Video Volume tool fixes audio that is too quiet or too loud. Boost whisper-quiet recordings so they are actually audible, or tame clips that blast at full volume — then download a balanced MP4.

Phone recordings often come out too soft, especially interviews and lectures. This tool amplifies the audio track cleanly without touching the video quality. You can also mute a video completely when you need a silent clip. All processing happens in your browser — nothing is uploaded.

How to Use It — Step by Step

1. Upload your video file above.
2. Drag the volume slider up to boost quiet audio, or down to quieten loud audio.
3. Preview to make sure the level sounds right.
4. Download the volume-adjusted MP4 — free, no watermark.

Popular Uses

• Interviews: boost quiet speech so every word is heard.
• Lectures: fix classroom recordings with weak audio.
• Loud clips: reduce harsh volume spikes and wind noise.
• Silent versions: mute a video for use as background footage.

Private by Design

Like every tool here, the Change Video Volume works 100% in your browser. Your files are processed on your own device and never uploaded to any server — which also means it is fast, private, and free to use.
