Volume Booster

Volume Booster features

• 01

  Boost by dB or percent

  Slide the gain from a gentle lift to a strong +20 dB. The value is shown in both decibels and percent so you know exactly how much louder the track will be.

• 02

  Clipping warning built in

  The tool analyzes the file's peak level and warns you when your chosen gain would push the audio past 0 dBFS and cause distortion, so you can back off before exporting.

• 03

  Normalize or preview live

  Turn on normalize (loudness normalization) for an automatic, even level, or preview your manual boost in real time before committing. Export as MP3 or keep the original format.

Volume Booster FAQ

How do I make an audio file louder?

Upload the file, raise the gain slider to the boost you want, preview it, then click Boost volume. Download the louder file when it finishes.

How loud can I make it?

Up to +20 dB, roughly a 900% increase in amplitude. Watch the clipping warning — pushing well past the file's headroom can introduce distortion.

What does the clipping warning mean?

It compares your gain to the loudest peak in the file. If the boosted peak would exceed 0 dBFS, the audio would clip and distort, so the tool flags it so you can lower the gain or normalize instead.

What is the normalize option?

Normalize applies loudness normalization to bring the whole track to a consistent target level automatically, which is ideal for uneven recordings without picking a manual gain.

Is my audio uploaded anywhere?

No. The volume boost is processed entirely in your browser, so your audio never leaves your device.
