Convert audio to MP3 or WAV

Drop in one recording or fifty and get MP3 or WAV files back. The conversion happens in this tab, so a voice memo or an interview never goes to anyone else's server.

How to convert an audio file to MP3 or WAV

STEP 1

Add your audio

Drop in as many files as you like. M4A, OGG, FLAC, WAV, MP3 and most others open.

STEP 2

Pick MP3 or WAV

MP3 is small and plays everywhere. WAV keeps every detail and is much larger.

STEP 3

Convert and save

Each file is listed with its new size. Save them one at a time.

Choosing between MP3 and WAV

An MP3 is usually about a tenth of the size of the same sound as a WAV, because it leaves out detail most ears do not notice. That is why it plays on every phone, car stereo and website. A WAV keeps everything and takes roughly ten megabytes for each minute, which suits editing and archiving more than sharing.

The quality setting is the bitrate. At 128 kbps speech sounds clean and the file stays small. For music, 192 kbps is a sensible default and 320 kbps is the highest an MP3 offers. Converting a low quality file to a high bitrate does not bring back what was already lost, it only makes the file bigger.

Each time sound is saved in a lossy format a little more is thrown away, so convert from the original when you still have it. Which files can be opened depends on your browser, and current versions of Chrome, Edge, Firefox and Safari handle all the common ones.

Questions

Is my file uploaded anywhere?

No. The work happens inside this tab, on your own machine. Open your browser's network tab while you use the tool, there is no request carrying your file.

Is there a file size limit?

None set by us. Very large files are limited only by your device's memory, and we warn you before that becomes a problem.

Do I need an account?

No, and there is no daily limit either. There is nothing to sign up for.

Which formats can it open?

Whatever your browser can play. That covers MP3, WAV, M4A, AAC, OGG, Opus and FLAC in current browsers.

Can it save as M4A, OGG or FLAC?

No. It saves MP3 and WAV, which between them cover nearly every use.

Why is my WAV so large?

A WAV stores the sound uncompressed. If you only need to listen to it or send it, MP3 is the better choice.
