# How to make a quiet video louder

Updated 2026-11-09

To increase video volume, raise the gain on the sound track and stop the loudest peaks from clipping. Increase Volume does this in your browser for a video or an audio file. Boost it by 3, 6, 10, 15, 20 or 30 dB, or even it out to a standard loudness. The picture is copied untouched, and nothing is uploaded.

## Raise the volume in four steps

Pick one video or audio file. The ffmpeg engine is about 32 MB and downloads once from a public CDN.

1. Choose a video or audio file.
2. Choose Boost to set an amount, or Even out to hit a standard loudness.
3. Press increase volume.
4. Read the measured before and after levels, then download.

## Boost or even out

Boost adds the number of decibels you pick, from 3 to 30. It keeps the gap between quiet and loud parts, so it suits a clip that is simply too quiet.

Even out aims for a loudness of -16 LUFS with peaks at -1.5 dB. It suits a recording where one speaker is loud and another is hard to hear. In our test the result landed within 1.5 of the target.

## Why loud audio distorts

Digital audio has a ceiling. Push a peak past it and the wave gets flattened, which sounds harsh. In Boost mode a limiter holds peaks near -1 dB. Our test output stayed below -0.3 dB.

If the clip is already loud, heavy limiting can sound squashed. The result note tells you how far the peaks would have gone and warns you if they still reach full scale.

## What happens to the picture and sound

The video is copied packet for packet, so quality is unchanged and the container stays the same. The sound is encoded again, as AAC in MP4, MOV and MKV, Opus in WebM, and MP3 in AVI.

## Questions

### Why does hiss get louder too?

The gain applies to the whole track, so noise rises with the voice. Run Noise Remover first, then raise the volume.

### How many decibels should I add?

Start with a small amount and read the measured levels in the result. Every extra step brings the peaks closer to the limiter.

### How many decibels equal 200% volume?

About 6 dB. Adding 6 dB doubles the wave height, which is what most players mean by 200%. A boost of 20 dB multiplies it by ten.

### Can I make an audio file louder, not a video?

Yes. The tool takes a video or an audio file and treats both the same way.
