Choose the format
Pick MP3, WAV, M4A, AAC, OGG or FLAC.
Choose the quality (optional)
For MP3, M4A, AAC and OGG pick a bitrate up to 320 kbps, or mix to mono for a voice recording.
Convert and download
Press Convert audio, listen to the result and download it.
Drop in an audio file, choose the format you need and download the converted file. MP3, WAV, M4A, AAC, OGG and FLAC all work as both the starting point and the result, so one page handles WAV to MP3, M4A to MP3, FLAC to MP3, MP3 to WAV and every other pairing - for songs, music libraries, voice memos, podcasts and recordings alike.
For MP3, M4A, AAC and OGG you choose the quality as a bitrate, from 64 kbps for small voice files up to 320 kbps, the best sound MP3 offers. WAV and FLAC are lossless, so they have no quality setting. A mono option mixes both channels into one, which suits voice recordings and halves the size of WAV and FLAC files.
Other file types usually work as the starting point too - WMA, AIFF, Opus and more - and you can drop in a video file to convert its sound track straight to an audio format. Play the original and the converted result on the page, then download the one you like.
The conversion happens in your browser. Your music and recordings are never uploaded, so it works on private files, there is no queue to wait in, and there is no limit on how many files you convert one after another.
If you are unsure which format to pick, MP3 plays on virtually everything, M4A and OGG make smaller files at similar quality, WAV keeps everything for editing, and FLAC keeps everything in a smaller file.
Add your file, choose the format you want to end up with and press Convert audio. The converted file appears with a player so you can check it, then download it. There is no sign-up, no watermark and no limit on how many files you convert.
MP3, WAV, M4A, AAC, OGG and FLAC can all be converted to each other, and most other common audio files - such as WMA, AIFF and Opus - can be used as the starting file. You can also add a video file to convert its sound.
Add the WAV file, choose MP3 and a quality - 192 kbps is a good everyday choice and 320 kbps gives the best sound - then press Convert audio. A WAV file is uncompressed, so the MP3 is a fraction of the size - about a tenth at 128 kbps and about a seventh at 192 kbps.
Add the MP3 file, choose WAV and press Convert audio. WAV has no quality setting because it is lossless. People convert MP3 to WAV so that editing software or hardware that needs WAV can open the file.
No. A WAV or FLAC made from an MP3 holds exactly the sound the MP3 had, in a bigger file - detail that was removed when the MP3 was made cannot come back. Lossless formats are best used when you start from a lossless original, such as a CD rip or a studio recording.
MP3 stores less detail than WAV to make the file smaller. At 192 to 320 kbps the difference is hard to hear in normal listening. If you need every detail, keep a WAV or FLAC copy as well.
Add the M4A file, choose MP3 and press Convert audio. This is the usual way to turn an iPhone voice memo or an iTunes-style M4A song into an MP3 that plays everywhere.
Add the file, choose MP3 and a quality, and press Convert audio. FLAC to MP3 is a popular way to put a music collection on a phone or car stereo that does not play FLAC.
MP3 plays on almost anything, which makes it the safe choice for sharing. M4A and OGG make smaller files at similar quality. WAV is uncompressed, so its files are large but hold all of the original sound, which suits editing. FLAC is also lossless but compressed, so it keeps all the quality in a smaller file than WAV.
The bitrate sets the quality in kilobits per second. 128 kbps is fine for speech and everyday listening, 192 kbps is a good all-round setting, and 256 to 320 kbps is for music you want to sound its best. A higher bitrate gives better sound and a bigger file.
Stereo audio has a left and a right channel. Mono mixes them into one, which is a good fit for speech, lectures and phone recordings. A WAV or FLAC file made this way is about half the size; an MP3, M4A, AAC or OGG file keeps the size of the bitrate you chose, so to make those smaller pick a lower bitrate or use the Audio Compressor.
Yes. Add an MP4 or WebM video, choose the audio format and the sound track is saved as an audio file. The Video to Audio Extractor has more format and quality choices for pulling sound out of a video.
No - they are different jobs. This converter changes the format of the sound, for example WAV to MP3. Turning speech into written text is called transcription, and it is done by speech-to-text tools.
No. The conversion runs inside your browser, on your own device, so your music and recordings are never sent to a server.
