About these tools

Turn a recording into an MP3, cut out the bits you don’t want, join several files into one, make a file small enough to email, or grab the soundtrack from a video. Free, and no sign-up.

Every tool tells you what you’re trading. Turning WAV or FLAC into MP3 makes the file much smaller for a small, usually unnoticeable, drop in quality. Converting an M4A to MP3 is only worth it if a device won’t play M4A. Pulling the sound out of a video loses nothing at all.

One rule worth remembering: you can always make an audio file smaller, but never better. Saving a low-quality MP3 at a higher setting just makes a bigger file that sounds the same.

No upload wait and no size limit — your files never leave your device. Using Firefox? If your browser can’t read a particular file, the tool tells you and suggests one that can.

Questions people ask

Can anyone else hear my files?

No. Everything is done on your device, and your files are never sent anywhere. Each tool shows a counter to prove it: 0 bytes sent.

Why does the first conversion take a moment to start?

The MP3 maker downloads once, the first time you use it. After that, conversions start straight away.

Which formats can I use?

WAV, MP3, M4A, AAC, FLAC, OGG, and Opus, plus MP4, MOV, WebM, and MKV videos if you want their sound. AIFF, AVI, and WMA don’t work in a browser.

Is there a size limit?

No limit from us. A 747 MB WAV converted here in about 21 seconds.

Will converting an MP3 to WAV improve it?

No. The detail an MP3 left out is gone for good — a WAV just makes the file bigger.
