Q: How much can I boost the volume?

You can boost volume up to 200% (2×) using the slider or preset buttons. Going above 100% may cause audio clipping if the original track is already loud.

About This Tool

This tool uses FFmpeg.wasm to adjust audio volume inside your browser using the volume filter. Set it below 100% to make audio quieter, or above 100% to boost it. Note that boosting above 100% on already loud tracks may cause clipping — use 150–200% on quiet recordings.

Frequently Asked Questions

Are my audio files uploaded to a server?

No. All volume adjustment is done using FFmpeg.wasm which runs entirely in your browser. Your files never leave your device and are never transmitted to any server.

How much can I boost the volume?

You can boost volume up to 200% of the original level. Use the slider to fine-tune the exact level you want, from silent (0%) all the way to double the original loudness.

Will boosting cause audio distortion?

Distortion (clipping) is possible if you boost already loud audio above 150%. If you hear crackling or distortion in the output, try a lower boost level or normalize the audio first.
