What Is Volume Adjustment?

Volume adjustment changes how loud a track plays back, without touching its pitch, tempo, or content. It's the same operation as turning a volume knob — just applied permanently to the audio file itself.

Reduce the volume of a track that's mixed too hot, or boost one that's too quiet compared to everything else in your library. Boosting beyond the original level can introduce some clipping on already-loud material — reducing is always clean.

Frequently Asked Questions

Is the volume adjuster really free?
Yes, completely free. No trial period, no credit card, no catch.
Will boosting the volume cause distortion?
If the source audio is already close to full volume, boosting it further can clip (a harsh, distorted sound) at the loudest moments. Reducing volume never causes this — it's always safe.
Does this change the tempo or pitch?
No. Volume adjustment only changes loudness — the pitch, tempo, and length of the audio stay exactly the same.
What audio formats can I upload?
You can upload MP3, WAV, FLAC, M4A, AAC, OGG, AIFF, and most other common audio formats. Maximum file size is 100 MB.
What format is the output file?
The volume-adjusted track is delivered as a high-quality MP3 file.
