How to make audio louder

Choose your audio file. Tap the box and pick a file from your phone or computer.
Set the volume. 100% is the original. 200% is twice as loud. Or tap the button to find the loudest clean level.
Keep distortion protection on. It softly limits the loudest parts so the sound doesn't crackle.
Tap Change volume and download. Play it before you save it, and lower the volume if it sounds harsh.

Very quiet recordings with lots of background noise get noisier when boosted. Record closer to the mic when you can.
Aim for a clear, even voice rather than the maximum volume.
Boost the file here before adding it to a video so you don't have to boost it in the editor.

How much can I boost the volume?

Up to 500%, which is five times the original level. Anything above the loudest clean level gets gently limited when protection is on.

Why does my audio sound distorted?

The volume is too high for the recording. Lower it, or keep distortion protection on.

Can I make it quieter?

Yes. Set the volume below 100%.

Do you keep my files?

No. We don't store your files.

Is it free?

Yes, with no signup and no watermark. The page shows ads from a third-party ad network, which runs its own code and may use cookies.
