Free Increase Video Volume

A video volume booster raises the loudness of a video’s soundtrack so speech and music are easier to hear. This tool applies a gain from 0% to 400% to the whole audio track, limits the peaks and exports the video again as an MP4.

1. Click Choose files and pick your video. 2. Enter a value above 100 in Original volume (%). 3. Click Create file. 4. Listen to the result, then click Download.

It doubles the audio signal’s amplitude before the limiter, which sounds clearly louder but not twice as loud to most ears. How loud it feels also depends on the recording and the speaker you play it on.

The limiter keeps peaks below full scale, which prevents hard clipping. At very high settings, though, the limiter works constantly and loud parts can sound squashed, so use the lowest value that makes the speech clear.

Yes. Enter a value below 100, such as 70 for a slightly quieter clip, or 0 to mute the audio completely while the picture keeps playing as before.

The video you chose has no sound to boost, which often happens with screen recordings made without a microphone or clips exported silent. Pick a file that has audio, or add a soundtrack with SocQ’s Add Audio to Video tool.

Yes, it’s free and requires no signup. The exported MP4 has no SocQ watermark or logo; the volume is the only thing that changes.

No. The audio is processed by FFmpeg in your browser, so the video stays on your device and isn’t sent to SocQ. Your browser downloads the video engine on the first run and caches it.

You can open MP4, WebM, MOV, MKV, AVI and other common video files up to 100 MB and 10 minutes, as long as they include sound. The result is an H.264 MP4 with AAC audio.

Yes. Open this page in your phone’s browser, choose the clip from your gallery and create the file. Processing happens on the phone, so a long video takes longer than it would on a computer.
