Privacy
Reading, demuxing, and encoding happen in your browser; neither the video nor output is uploaded.
Requirements
Input is limited to 500 MB and estimated output must remain below 256 MiB. Container decoding and MP3, AAC, Opus, or FLAC encoding depend on the browser, so even WAV may be unavailable for a particular input.
Common questions
- Can every MP4 be converted to MP3?
- No. MP3 is offered only when this browser can read the MP4 audio track and encode MP3.
- Which track is used when a video has several audio tracks?
- The tool uses the container's primary audio track, based on default flags and track information.
- Are video or location tags kept?
- No. Video tracks and descriptive source metadata are not copied into the audio output.
