Adjust Audio Volume Online for Free
Make your audio louder or quieter the way that suits your file. Boost a quiet recording by a set amount, normalize it to the loudest it can go without clipping, or aim for a specific target peak level. An optional limiter helps keep boosted audio from distorting. The result downloads in the same format you uploaded. No sign-up and no watermarks.
Three Ways to Adjust Volume
- Manual Gain – raise or lower the volume by a set amount, from −20 dB (quieter) to +20 dB (louder)
- Normalize – automatically push the volume to the maximum level without clipping — great for quiet recordings
- Target Peak – set an exact peak level (from −20 to −0.1 dB) for consistent loudness across files
How to Adjust Volume
- Click the upload area above or drag and drop your audio file (up to 10 MB).
- Pick a mode — Manual Gain, Normalize, or Target Peak — and set the slider. Keep the limiter on to avoid clipping when boosting.
- Apply and download your adjusted audio.
Common Use Cases
- Quiet recordings – boost audio captured at low microphone levels
- Consistent levels – normalize or target-peak several files to match
- Presentations – make clips loud enough for room playback
- Background music – turn music down before laying it under a voice
- Phone & voice memos – amplify quiet call recordings
Frequently Asked Questions
Manual Gain changes the volume by a fixed amount you choose (say +6 dB). Normalize is automatic — it raises the audio to the loudest it can be without clipping, so you don't have to guess the right number.
Large boosts can clip. Leave the limiter on (it's on by default) and the tool reins the level back in after a positive boost to keep things clean. Very quiet sources may only boost so far before the noise comes up too.
Volume changes how loud the audio sounds (its amplitude). The bitrate tool changes the encoding quality, which affects file size — not loudness.
You can upload MP3, WAV, OGG, FLAC, AAC, M4A and WMA up to 10 MB, and the result downloads in the same format. (WMA files are returned as WAV.) Need a different format? Use our Convert Audio tool.
