Overview

Easily adjust the audio volume of your video files online. This tool allows you to boost quiet audio up to 500%, lower loud soundtracks, or completely mute videos, while offering the option to copy the video stream directly without re-encoding to preserve original video quality and speed up processing.

When to Use

  • •When a recorded video has barely audible speech and needs its volume boosted.
  • •When you need to completely mute the background audio of a video before sharing it.
  • •When you want to adjust video sound levels quickly without losing original video quality through re-encoding.

How It Works

  • •Upload your video file in MP4, WebM, MKV, AVI, or MOV format.
  • •Adjust the volume slider from 0% (mute) up to 500% (maximum amplification).
  • •Choose your preferred output format and toggle the 'Copy Video' option to bypass video re-encoding for faster processing.
  • •Process and download your adjusted video file with the updated audio levels.

Use Cases

Amplifying quiet dialogue in lecture recordings or presentation videos.
Muting background noise or unwanted audio from video clips before uploading them to social media.
Balancing audio levels across multiple video clips to ensure consistent volume.

Examples

1. Boost Quiet Lecture Audio

Online Student
Background
A student downloaded a recorded lecture video, but the professor's voice is extremely quiet and hard to hear even at maximum device volume.
Problem
The audio needs to be amplified significantly without degrading the video quality or taking too long to process.
How to Use
Upload the lecture MP4, set the volume slider to 250%, keep 'Copy Video' checked to avoid re-encoding, and select MP4 as the output format.
Example Config
Volume: 250%, Output Format: MP4, Copy Video: Enabled
Outcome
The student receives a new MP4 video where the professor's voice is loud and clear, processed instantly without any loss in video resolution.

2. Mute Background Noise for Social Media

Content Creator
Background
A creator captured a great B-roll video outdoors, but the background wind noise is distracting and needs to be removed before adding a voiceover later.
Problem
The original audio track must be completely silenced while keeping the video stream untouched.
How to Use
Upload the raw MOV video file, set the volume level to 0%, select WebM as the output format, and run the tool.
Example Config
Volume: 0%, Output Format: WebM, Copy Video: Disabled
Outcome
A silent WebM video is generated, ready for clean voiceover integration in external editing software.
