Convert MKV to MP3

How it works

1. Drop a .mkv file (or any video) onto the page.
2. The MP3 output preset is already selected — hit Convert Now.
3. Download the result. The whole conversion ran in your browser via WebCodecs or FFmpeg.wasm. No file left your device.

Why convert MKV to MP3?

Extract MP3 audio from an MKV / Matroska video file.

Is my file uploaded anywhere?

No. poqpoq is a static site — the page you're looking at is a bunch of JavaScript your browser downloaded once. It runs entirely on your device. There is no upload endpoint. When you open your browser's Network tab during a conversion, you'll see zero requests going out.
