or click to select it
Turn the volume of an audio file up or down directly in your browser, without needing to install a full audio editor for such a simple adjustment.
Multiplies the audio signal's amplitude by the chosen factor. Boosting the volume of an already-saturated recording a lot can introduce distortion (clipping), since it can't recover information that was never captured in the first place.
Use cases
- Boost the volume of a voice recording that's too quiet.
- Lower the volume of an uncomfortably loud audio file before sharing it.
- Match the volume level of several clips before merging them.

Frequently asked questions
Can I fix a distorted recording by raising the volume?
No — if the original audio is already clipping, raising the volume only makes the distortion more obvious, it doesn't fix it.
What happens if I raise the volume too much?
Audible distortion can appear if the signal exceeds the maximum the format can represent. If that happens, try a lower percentage.
