3 Free Audio tools

Audio tools

MondayKit audio tools run on your device. The voice recorder uses the microphone in this tab and never uploads the recording. Conversion and cutting load ffmpeg.wasm when you run them. A phone shows a warning because that library is large.

Frequently asked questions

Is my recording uploaded?

No. The microphone stays in this tab. The file is yours to download, and closing the page clears it.

Why does conversion ask me to wait?

MP3, WAV and OGG conversion uses ffmpeg.wasm, which is a large library. The first run loads it. Your audio is not sent to a server.

Can I make a ringtone?

The audio cutter lets you choose a start and end, then download that clip. What a phone accepts as a ringtone depends on the phone.

Do I need an account?

No. The tools run in the browser with no signup.
