You can convert MKV to M4A for free: upload your MKV above and Flippy extracts the audio as M4A in your browser, no signup needed.

Turning MKV into M4A 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 an M4A built for sounding great anywhere in the Apple ecosystem.

Why flip MKV to M4A

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.

M4A is AAC in Apple's favorite outfit: the audio-only MP4 your iPhone speaks natively. An MP4 container holding only audio: usually AAC, occasionally Apple's lossless ALAC. That makes it the right destination when what you need is sounding great anywhere in the Apple ecosystem.

Questions people ask

Will converting MKV to M4A 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 M4A will sound like.

Will the M4A 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 like AAC: better-than-MP3 sound at about 1 MB per minute.

Where will the M4A file play?

iPhone, Mac and iTunes natively; most modern Android and Windows apps too. That's the usual reason people leave MKV behind: M4A simply opens in more of the places that matter.

How long does MKV to M4A 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.
