Can I make an audio file louder?

Yes. You can boost the volume by a set amount. For very quiet recordings, normalize often gives the best result without distortion.

What does normalize do?

Normalize raises the audio so its loudest peak reaches a target level, giving a consistent, full volume without clipping.

Is my audio uploaded anywhere?

No. All processing runs in your browser using the Web Audio API, so your file never leaves your device.

Which formats can I load and save?

You can load MP3, WAV, M4A, AAC, and OGG files, and export the result as MP3 or WAV.

Will boosting the volume reduce quality?

Raising volume too far can cause clipping and distortion. Normalize avoids this by stopping at the peak. Exporting to WAV keeps a lossless result.

Does it work on mobile?

Yes. It runs in any modern browser on Windows, macOS, Android, and iOS, though long files process faster on a desktop.

Yes. There are no watermarks, sign-ups, or file-size limits beyond what your device can handle.
