While extracting audio from an MP4 file to FLAC format, our converter carefully processes the audio stream to ensure the highest possible quality is maintained. If the original MP4 file contains high-quality audio, the resulting FLAC file will preserve all of that fidelity. However, it's important to note that if the original MP4 already uses lossy compression (like AAC), converting to FLAC will maintain that quality but cannot restore any data that was already lost in the original compression.

Frequently Asked Questions
Can converting to FLAC improve my audio quality?
Converting to FLAC won't improve the quality of audio that's already been compressed with a lossy codec (like AAC in most MP4 files). However, it will preserve the existing quality without any further degradation. Think of FLAC as a perfect container that prevents any additional quality loss during storage or future conversions. For the highest quality results, start with source material that hasn't been heavily compressed.
Why are FLAC files so much larger than MP3 or AAC?
FLAC files are larger because they preserve all of the original audio data without discarding any information. While FLAC does use compression (typically reducing file size by 50-60% compared to completely uncompressed audio), it's lossless compression, meaning it can be perfectly restored to its original state. Lossy formats like MP3 and AAC achieve smaller sizes by permanently removing data deemed less perceptible to human hearing, which is why they can be 5-10 times smaller than lossless formats.
Which applications and devices support FLAC playback?
FLAC is widely supported by audiophile and professional audio software including VLC Media Player, foobar2000, JRiver Media Center, and many others. Most Android devices support FLAC natively, and it's becoming more common in high-end audio hardware. On iOS, apps like VLC for Mobile can play FLAC files. Some streaming services like Tidal and Amazon Music HD also offer FLAC or similar lossless quality options. Windows 10/11 includes native FLAC support, while macOS users may need third-party players.
