Read the full guide for MP3 volume boosting, batch volume control, and clipping-aware settings for recordings, podcasts, lessons, and media assets.
How much can I change the volume?
The tool supports 0% to 500% gain. 100% keeps the original volume, lower values reduce volume, and higher values boost it.
Can boosting volume cause clipping?
Any audio can clip if boosted too much. The tool applies a simple clipping guard, but starting between 120% and 200% is usually safer.
Which audio formats are supported?
The tool supports common formats your browser can decode, such as MP3, WAV, M4A, and OGG. Output is WAV.
Are audio files uploaded to a server?
No. Decoding, waveform preview, volume processing, and WAV export happen locally in the browser.
