Normalise audio volume
Bring quiet recordings up to a usable level — and a whole batch to the same level, so you stop reaching for the volume knob between files.

Frequently asked questions
Which bitrate should I pick?
192 kbps sounds transparent to most ears, 128 kbps is the classic size for sharing, and 96 kbps still fits almost any inbox. Going higher than the original never adds quality — it only adds bytes.
Does the length change?
No. Converting and compressing keep the full length; only trimming shortens the file, and there you set the start and end yourself.
Are my files uploaded to a server?
No. The whole job runs inside your browser, on your own device. Your file never travels over the network, so there is nothing for us to store, read or lose.
Does it cost anything?
No. There is no account, no trial and no upload limit tied to a plan.
Does this work on a phone?
Yes, on Android and on iPhone. The browser does the work, so no app has to be installed.
How large can a file be?
The limit is your device's memory rather than a rule we set. Very large files work on a computer and can fail on an older phone.
