How to use this tool

- Click Extract Audio and download the result.
Frequently asked questions
- What video formats can I use?
- Any format your browser can decode — MP4, WebM, MOV, and MKV all work in most current browsers, since decoding happens through the browser's own built-in codecs.
- What happens to the video part?
- It's discarded — only the audio track is decoded, re-encoded to your chosen format, and downloaded. The video itself is never re-encoded, so extraction is fast.
- Which output format should I pick?
- MP3 for the smallest, most universally compatible file. WAV or FLAC if you need lossless quality for further editing — they'll be much larger. OGG is a good lossy alternative to MP3 with similar file sizes.
- Is my video uploaded anywhere?
- No — the audio track is decoded and re-encoded entirely in your browser. Nothing is uploaded.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical online tools |
|---|---|---|
| Data ever leaves your device | No — extracted in this tab | Yes, uploaded to process |
| 4 output formats, with an optional trim | Yes | Varies — some tools only offer one format |
| Account required | Never | Often, past a certain usage level |
