Turning MP4 into FLAC isn't really a conversion: it's an extraction: Flippy lifts the audio track out of your MP4 and re-packs it on its own. You keep the sound and drop the pixels, swapping an MP4 that runs roughly 50–100 MB per minute at 1080p, depending on bitrate for a FLAC built for archiving music with zero quality loss and a genuine size saving.

Why flip MP4 to FLAC

MP4 is the world's default video: the file that plays before anyone has to think about it. It was born in 2001, the MPEG standards group, built on Apple's QuickTime design, and its real weak spot is very little day to day: as a container its quality depends on the codec inside.

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 MP4 to FLAC lose quality?

No: extraction copies the audio that's already in the MP4. 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 MP4?

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 MP4 behind: FLAC simply opens in more of the places that matter.

How long does MP4 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.
