Convert video to audio

How it works

1. 1

   Add your video

   Drop in the video whose sound you want to keep.

2. 2

   Choose a format

   MP3 for the smallest file, WAV for lossless, or AAC.

3. 3

   Download

   Save the audio track. It downloads straight from your machine.

Choosing a format and bitrate for the audio you pull out

MP3 is the safe answer. It is the only audio format you can hand to anyone, on any device, from any decade, and be confident it will play. It is not the most efficient codec anymore, but universal support is worth more than the last few percent of efficiency in almost every situation where someone wants an audio file out of a video.

M4A, which carries AAC, is the better format on the merits: at the same bitrate it sounds noticeably cleaner than MP3, particularly on cymbals, applause, and other high frequency detail where MP3 struggles. It plays everywhere that matters today. WAV is lossless and enormous, and is worth choosing only if the audio is going into an editor for further work.

Bitrate is where people overspend. Speech, which covers lectures, podcasts, interviews, and meeting recordings, is transparent at 96 to 128 kbps and gains nothing above it. Music wants 192 to 256 kbps. Nothing you choose can exceed the quality of the audio already inside the video, so exporting a 320 kbps MP3 from a video whose soundtrack was a 128 kbps AAC produces a larger file, not a better one.

Convert video to MP3 in your browser, with no upload

The video is decoded on your machine and the audio written straight back to your downloads folder. No upload, no length limit, no account, and no watermark or spoken tag stitched onto the result, which some free converters still do.

Because there is no server, there is also no queue and no failed job because someone else's converter was busy. A long recording simply takes as long as your own machine needs.

If you want the audio track exactly as it already exists inside the video, with no quality lost to a second encode, the audio extractor copies it out rather than converting it. To cut the result down to a single passage, use the audio trimmer.

Why nothing uploads

Other tools send your video to their servers, which costs them money per file, so they add watermarks, cap file sizes, and make you sign up. This tool does the work right here in your browser using your own device. Your file is never uploaded, so there is no wait, no watermark, no size limit, and no account.

Questions

What is the difference from the audio extractor?

Nothing, this is the same tool named for converting a whole video into an audio file. Both save the soundtrack as MP3, WAV, or AAC.

Does my video get uploaded?

No. The conversion runs in your browser; your file never leaves your device.

Is it free?

Yes, no account, no watermark, no size limit.
