Frequently Asked Questions

How do I convert MKV to MP3 online?
Drop your MKV video onto the page and click Extract. The MP3 downloads to your device. Everything runs in your browser — nothing is uploaded.
Is my video uploaded?
No. All extraction happens entirely in your browser. Your MKV file never leaves your device. See our privacy policy.
Why is the first extraction slower?
FFmpeg loads on first use (a ~25 MB WebAssembly module). After that, all subsequent extractions in the same browser session are fast.
Can I extract audio in a different format?
Yes — the output format dropdown supports WAV, OGG, FLAC, AAC, and M4A in addition to MP3.
