Top 10 YouTube to FLAC Converters in 2025 [PC/Mac/Online]

Part 1: What is FLAC?

FLAC (Free Lossless Audio Codec) is an open-source lossless audio compression format. It can significantly reduce the file size while maintaining the original audio quality, so it is loved by music lovers and professional audio workers. When you need to convert YouTube videos to audio, if you want to avoid sound quality loss, FLAC format is one of the best choices because it can completely retain the audio data without causing quality loss during the transcoding process.

Advantages of FLAC

1. Lossless Audio Quality: FLAC format does not lose audio details like lossy formats such as MP3. It is suitable for listeners who have high requirements for sound quality.

2. High Compression Efficiency: Compared with lossless WAV format, FLAC can effectively reduce the file size, usually compression ratio between 30% and 60%.

3. Strong Compatibility: FLAC format is widely supported by many modern audio players (VLC, Foobar2000, Audirvana, etc.). In addition, FLAC files can be played on most high-end audio devices.

4. Metadata Support: FLAC files support rich metadata (album art, artist information, lyrics, etc.). It means that it can embed a variety of additional information related to the audio content, making the music file management more complete.

5. Open Source and Free: FLAC is an open source format, which means it is not restricted by patents, and users are free to use and distribute FLAC files without paying any fees.

Disadvantages of FLAC

1. File Size: Although FLAC files are smaller than the uncompressed WAV format, they are still much larger than other lossy formats like MP3. This may impose some limitations on storage space and transfer speeds.

2. Limited Player Compatibility: Some low-end devices or default system players may not be supported. For example, Windows Media Player and Music.app for macOS do not support the FLAC format by default and require additional plug-ins to be installed.

3. Unsupported Streaming Services: Most major music streaming services (e.g., Spotify, Apple Music) don't support FLAC format because they need a more efficient lossy format for smooth online playback.
