Video Volume Booster

After recording a video, you may notice that voices are too quiet, background music is too loud, or the audio feels weak after uploading to social media. Opening a full video editor just to adjust one audio track is often too much work for short clips, review videos, and quick social posts.

This Video Volume Booster loads MP4, MOV, and WebM videos in your browser and lets you adjust volume from 50% to 500%. Boost quiet videos to 150%, 200%, or 300%, or lower overly loud videos to 50% or 75%. The tool applies an audio volume filter while keeping the workflow focused on one practical task: making video sound easier to hear or more comfortable to play.

All processing runs locally in the browser, and your video is not uploaded to an external server. It is suitable for family clips, work review videos, face-recorded footage, and social media drafts that should remain private. Use it when recorded speech is too quiet, a meeting clip needs louder voices, or background audio needs to be reduced before sharing.
