Convert MP3 to FLAC

How it works

1. Drop a .mp3 file (or any audio) onto the page.
2. The FLAC 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 MP3 to FLAC?

Convert MP3 to FLAC. MP3 already threw away some audio, so FLAC won't make it sound better — but it gets you into a lossless container for archiving alongside other FLAC files.

You might also want to convert MP3 to WAV, convert WAV to MP3, convert FLAC to MP3, convert FLAC to WAV, convert M4A to MP3, convert OGG to MP3, convert AAC to MP3, convert MP3 to OGG, convert WAV to ALAC, convert FLAC to ALAC, convert MP3 to ALAC, convert WAV to FLAC, or convert ALAC to FLAC.

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.
