That’s the point of lossless compression. FLAC is decompressed to a large size on playback. A 3-minute song from YouTube might be 3 MB as Opus, but becomes a 25 MB FLAC file. You’ve added empty space, not quality.
: Unlike MP3, FLAC is a lossless format, meaning it decompresses to an identical copy of the original data. Rich Metadata

If you're serious about building a high-quality music library, the "ending" to this story isn't on YouTube. Instead, audiophiles often:
However, using FLAC for YouTube audio involves a major technical misunderstanding. This guide explains how audio compression works on video platforms, why FLAC downloads might not give you the quality you expect, and how to get the absolute best audio possible from YouTube. Understanding the YT FLAC Misconception
: A web-based tool that handles 24-bit/96kHz quality without requiring software installation. If you want to set up the best
Use --audio-quality 0 or FLAC compression level 5-8. Higher compression (level 8) makes the file smaller but takes longer to encode. Quality remains identical.
If you use a standard online "YT to FLAC" converter, the tool downloads the compressed, lossy audio track (like a 160 kbps Opus file) from YouTube's servers. It then takes that low-bitrate file and re-encodes it into a FLAC container.
To ensure you get the absolute best audio possible when converting from YouTube to FLAC, follow these quality-control steps: A 3-minute song from YouTube might be 3
| Aspect | FLAC (Lossless) | MP3 (Lossy) | | :--- | :--- | :--- | | | Preserves 100% of the original source's detail | Discards audio data, degrading quality | | File Size | Large (approx. 30 MB for a 3-minute track) | Small (approx. 3-10 MB) | | Use Case | Archiving, Hi-Fi systems, future transcoding | Casual listening, portable devices with limited space | | Editing | Can be edited and re-encoded without quality loss | Editing and re-encoding causes further, permanent quality loss | | Ownership | The "Master Copy," forever usable | A "Delivery Format," prone to degradation |
