Extract audio from MP4 as FLAC
About MP4 to FLAC
For archiving or audiophile listening, you want sound that's compressed without losing a single detail. FLAC does exactly that, keeping full quality while taking less space than uncompressed WAV. This tool extracts the audio from your MP4 and saves it as FLAC.
Upload your .mp4 video and the converter pulls the audio and encodes it as lossless FLAC, perfect for archives and high-fidelity playback. Everything happens in your browser, free, with no watermark and no account required. Your file is processed only for the extraction and isn't kept, so your audio stays private from upload to download.

FAQ
Is FLAC really lossless?
Yes. FLAC compresses audio without discarding any detail, so it sounds identical to the source while saving space.
Why pick FLAC over WAV?
Both are lossless, but FLAC files are smaller because they use compression that doesn't sacrifice quality.
Will every device play FLAC?
Most modern players and apps support FLAC, but some older or basic players may need MP3 or AAC instead.
Can I use MP4 to FLAC on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
