How to make audio louder

  1. Drop your file in. Choose or drag an MP3, M4A, WAV, OGG or FLAC — it loads in your browser and is never uploaded.
  2. Set the boost. Move the Boost slider up to make it louder; the panel shows the resulting peak. Keep Prevent clipping on so it never distorts.
  3. Boost & download. Save the louder audio as MP3 or WAV.

Frequently asked questions (5)

Is it free?

Yes — completely free, with no sign-up, no watermarks, and no limit on how many files you process.

Will boosting distort my audio?

Not with Prevent clipping on (the default): the boost is capped so the loudest peak stays just under 0 dB. Turn it off only if you want maximum loudness and accept possible clipping.

Are my files uploaded anywhere?

No. Analysis and processing happen locally in your browser, so your audio never leaves your device.

What's the difference from the Normalizer?

The Normalizer auto-levels to a target loudness; the Volume Booster gives you a manual gain slider to make a file as loud as you want (clip-safe).

Which formats can I use?

Whatever your browser can decode — MP3 and WAV work everywhere, with M4A, OGG and FLAC where supported. The result is saved as MP3 or WAV.
