What is FLAC?

FLAC (Free Lossless Audio Codec) is an open-source audio format that compresses audio without any loss in quality. When you decode a FLAC file, you get the exact same audio data as the original source - bit for bit identical. This makes it perfect for archiving CD collections and for audiophiles who want the highest possible quality.

Why Convert to MP3?

While FLAC preserves perfect quality, MP3 offers practical advantages for everyday use. A 320kbps MP3 file is perceptually transparent - meaning most listeners cannot distinguish it from the original in blind tests. With files 60-70% smaller, you can store more music on your device and stream more efficiently.

Choosing the Right MP3 Bitrate

When converting from FLAC, choosing the right bitrate is crucial. Higher bitrates preserve more audio detail from your lossless source.

info Understanding Lossless vs Lossy Audio

Lossless (FLAC, WAV, ALAC)

Lossless compression reduces file size without discarding any audio data. Like a ZIP file for audio - when decompressed, you get the exact original. FLAC typically achieves 50-60% compression while maintaining perfect quality. Ideal for archiving and source files.

Lossy (MP3, AAC, OGG)

Lossy compression removes audio information that humans are less likely to perceive (psychoacoustic modeling). This achieves much smaller files (90%+ reduction) with quality that's often indistinguishable to casual listening. Perfect for portable use and streaming.

Pro Tip: Always keep your original FLAC files as your master archive. Converting FLAC to MP3 is a one-way process - you cannot restore lossless quality from an MP3 file.
