For OGG (or if your browser can’t read the file), the transfer is encrypted (HTTPS) and the file is deleted from our servers as soon as the conversion is done: it is never kept, listened to or shared.

Frequently asked questions

Is this audio converter really free?

Yes, completely. No fees, no subscription and no sign-up: you don’t need to create an account or log in to convert your audio files.

Are my files kept private?

Yes. To MP3 and WAV, and depending on your browser to AAC, M4A and FLAC, the conversion happens on your device: the file is not sent. Otherwise (OGG, rare format, older browser), it is sent over an encrypted connection (HTTPS), converted in a temporary folder and deleted immediately. We keep no copy, nobody listens to your files, and they are never shared or reused.

Which formats are supported?

You can upload MP3, WAV, OGG, AAC, FLAC, M4A or WMA audio files, as well as videos (MP4, MOV, AVI, MKV, WebM…), up to 1 GB, and convert them to MP3, WAV, OGG, AAC, FLAC or M4A.

Which audio format should I choose?

MP3 plays everywhere. M4A and AAC suit iPhone and the Apple ecosystem. WAV is uncompressed, ideal for editing. FLAC is lossless but smaller than WAV, perfect for archiving music. OGG is an open format common on the web and in games.

Does converting reduce quality?

WAV and FLAC are lossless. MP3 (about 190 kbps), AAC and M4A (192 kbps) use high-quality settings, with a difference that is usually inaudible. Note: converting an MP3 to WAV or FLAC does not restore quality that was already lost.

Can I extract the audio from a video?

Yes. Just upload a video (MP4, MOV, AVI, MKV, WebM…) and choose an audio format: only the soundtrack is kept.

Does the converter work on a phone?

Yes. It runs in the browser on iPhone, Android, tablets, Mac, Windows and Linux: for example, you can turn an iPhone M4A voice memo into MP3 without installing an app.
