Convert Video to MP3
Save the sound from any video as an MP3. It works with phone, camera, screen and downloaded recordings in every common format, and the video never leaves your device.
Your file never leaves your device. How?

When to turn a video into MP3
Often only the sound matters: a lecture or sermon to listen to while commuting, a recorded interview to transcribe, a band rehearsal filmed on a phone, a speech from a wedding video, or background music for another project. An MP3 is a fraction of the video's size and plays on anything.
If you know the format, the dedicated pages explain its quirks: MP4 to MP3, MOV to MP3 for iPhone videos, WebM to MP3 for browser recordings, and MKV or AVI to MP3. This page accepts all of them.
What happens to your video
FFmpeg in WebAssembly reads the video's first audio track and encodes it as MP3. The picture is skipped completely, so the video codec (H.264, HEVC, VP9, AV1 or anything else) doesn't matter and the job finishes quickly.
The video is read in pieces rather than loaded into memory, so large recordings work: up to 4 GB and 4 hours on a computer, or 2 GB and 2 hours on a phone.

Frequently asked questions
Is my file uploaded anywhere?
No. The conversion runs in your browser with a WebAssembly build of FFmpeg. Your file is read from your device and the result is saved back to it; nothing is sent to our servers.
Which video formats work?
MP4, MOV, M4V, MKV, AVI, WebM, 3GP and most others that contain an audio track. If a file has no audio, the tool says so instead of producing a silent MP3.
Can I convert a YouTube or Instagram link?
No. The tool converts video files that are already on your device. It doesn't download from websites.
Which bitrate should I pick?
192 kbps (High) sounds transparent for most music and is the default. 128 kbps is plenty for speech such as lectures and voice notes. 320 kbps only helps if the source audio is already high quality; it cannot add detail that isn't there.
How large a file can I convert?
Files up to 4 GB and 4 hours long on a computer, or 2 GB and 2 hours on a phone. The video is read in pieces rather than loaded into memory, so large recordings work; only the audio file being written has to fit in memory.
Is M4A better than MP3 for video audio?
Most MP4 and MOV videos already contain AAC audio. Choosing M4A with Original quality copies it without re-encoding, which is faster and lossless. Choose MP3 when the file must play everywhere.
