video tool
Extract audio from video
Extract audio from MP4 (tries stream-copy / AAC / MP3) using ffmpeg.wasm.
How it works
- Extract audio from MP4 in your browser: MP3 when the build supports it, otherwise AAC in an M4A file. Large files may be slow or fail depending on device memory.
FAQ
- Are my files uploaded to your servers?
- No. By default, Awesome Tools processes files entirely in your browser. Nothing is sent to our servers for conversion.
- Why did my conversion fail?
- Large files, unusual codecs, or browser memory limits can cause failures. Try a smaller file or a different browser. See the limits on this page.
