About The Audio Volume Booster
Ever record a video or voice note where the audio is way too quiet? This tool can artificially boost the volume up to 400%.
It works on both Audio files (MP3, WAV) and Video files (MP4, WEBM). If you upload a video, the visual track is instantly copied over without quality loss while the audio track is re-encoded at a higher decibel level.
How to Use
- Upload an audio or video file.
- Drag the slider past 100% to boost the volume, or below 100% to quiet it down.
- Click Apply Volume Change.
- Preview the new loudness and download the file.
Frequently Asked Questions
Will boosting the volume cause distortion?
Yes, if you push it too high. The FFmpeg engine will forcefully amplify the audio waves. If you boost a quiet file to 200%, it will sound great. If you boost a normal file to 400%, the audio will clip and sound distorted. Use the built-in preview to check before downloading.
Are my files uploaded to a server?
No. The audio is processed securely inside your own device using WebAssembly.
