About this tool
Convert and extract audio online: switch between MP3, WAV, M4A and OGG, set bitrate, sample rate and mono, cut the part you need, or pull the sound straight out of an MP4, MOV or other video. Audio is decoded and encoded in your browser and never uploaded.
Typical uses
- Extract the audio of a lecture or meeting video as MP3 for listening
- Turn a recording into WAV for an editor, or into MP3 to save space
- Cut a section of a song for a ringtone or alert sound
How to use
Choose an audio or video file, then MP3, WAV, M4A or OGG output, with bitrate, sample rate and mono as needed.
Optionally open the cut settings to choose start and end times, click Convert or Extract audio, listen and download.
Reads MP3, WAV, M4A, AAC, OGG, FLAC and the audio inside MP4, MOV, WebM and MKV. MP3 uses a bundled LAME encoder (about 400 KB on first use); M4A and OGG depend on browser encoding support. Converting between lossy formats loses a little quality.
Frequently asked questions
Can I extract MP3 from a video?
Yes. Choose an MP4, MOV, WebM or MKV video, select MP3 and click Extract audio. The picture is discarded.
Which MP3 bitrate should I use?
Speech sounds fine at 64–96 kbps; for music use 192 kbps, or 320 kbps for the best quality. Higher bitrates make larger files.
Why are the M4A or OGG buttons disabled?
These formats rely on the browser’s built-in encoders, and some browsers, such as certain Firefox or Safari versions, lack one of them. MP3 and WAV work in every supported browser.
