What is FLAC?

FLAC (Free Lossless Audio Codec) is a lossless audio format that preserves original quality while compressing file size better than WAV.

Why convert FLAC to MP3?

MP3 files are much smaller and more widely supported by devices and platforms. Converting makes your audio more portable while maintaining good quality.

Will I lose quality converting FLAC to MP3?

Yes, MP3 is a lossy format. However, at 320 kbps, the quality difference is minimal for most listeners and files become significantly smaller.
