You can convert MKV to FLAC for free: upload your MKV above and Flippy extracts the audio as FLAC in your browser, no signup needed.

Turning MKV into FLAC isn't really a conversion: it's an extraction: Flippy lifts the audio track out of your MKV and re-packs it on its own. You keep the sound and drop the pixels, swapping an MKV that runs as big as whatever you put inside: movie files often run to several gigabytes for a FLAC built for archiving music with zero quality loss and a genuine size saving.

Why flip MKV to FLAC

MKV is the format that hoards: video, a dozen audio tracks and every subtitle, all in one box. It was born in 2002, the open-source Matroska project, and its real weak spot is playing on TVs, iPhones and editors that never learned to open the box.

FLAC is the audiophile's handshake: CD-perfect sound at roughly half the shelf space. Free Lossless Audio Codec: think ZIP for sound: it decompresses back to the exact original. That makes it the right destination when what you need is archiving music with zero quality loss and a genuine size saving.

Questions people ask

Will converting MKV to FLAC lose quality?

No: extraction copies the audio that's already in the MKV. Whatever the soundtrack sounded like inside the video, that's what your FLAC will sound like.

Will the FLAC file be bigger or smaller than my MKV?

Much smaller: you're keeping the audio and dropping the video, which is most of the weight. Expect around 5 MB per minute: half of WAV, five times an MP3.

Where will the FLAC file play?

Hi-fi gear, Android, VLC, most desktop players; iTunes and Apple Music look away. That's the usual reason people leave MKV behind: FLAC simply opens in more of the places that matter.

How long does MKV to FLAC conversion take?

It scales with length and resolution: short clips finish in seconds, long HD videos can take a few minutes. Files auto-delete within an hour after.
