An MP3 converter takes an audio or video file and turns it into MP3, or takes an MP3 and turns it into WAV, AAC, OGG and a few other formats. Everything happens online, so there is nothing to install and no account to create.
How to convert to MP3
- Upload the file in the box above — audio, video, almost any common format works.
- Choose the output format. Pick MP3 if you’re converting from something else, or WAV, AAC or OGG if you’re converting an MP3.
- Wait a moment, then download the converted file.
When you need an audio converter
- You downloaded a video and only want the audio as an MP3 to listen to later.
- A voice recording came out as M4A on your phone, and the app you’re uploading it to only takes MP3.
- An old WAV file from a recorder or a ripped CD is too large to send, and MP3 would be a fraction of the size.
- Your car stereo or an old MP3 player only reads MP3 files, but your music is saved in AAC or OGG.
What this MP3 converter handles
It converts both ways: MP4 to MP3, WAV to MP3, M4A to MP3, and MP3 out to WAV, AAC or OGG. Send the file, pick the format, and the conversion runs on its own — you don’t need to know bitrates or codecs to get a clean MP3 at the end.
Limits and tips
- Very long or very large files take longer to convert, so give it a minute on anything over an hour of audio.
- Uploaded files are deleted within an hour, so download your result before you close the tab.
- If the output sounds off, check the format you picked before re-uploading — most issues come from converting the wrong way by mistake.
