Why convert FLAC to MP3?
FLAC preserves audio efficiently but is not accepted everywhere. A 128 kbps MP3 is smaller and convenient for quick sharing, previews, and devices with limited storage.
What happens to quality?
This changes a lossless source into a lossy MP3 at a fixed 128 kbps. Keep the FLAC as your master; the MP3 is best treated as a portable copy rather than an archival replacement.
Browser limitations
The browser must support FLAC decoding before the tool can encode the MP3. Modern browsers generally do, but older devices may not, and large high-resolution FLAC files can use significant memory.
