Why Convert FLAC to MP3?
FLAC preserves every bit of the studio master, and it charges for the privilege in file size.
Converting to 320 kbps MP3 trades fidelity you almost certainly cannot hear for a file roughly a tenth the size, which is what makes a lossless library practical to carry around and play.

Frequently Asked Questions
What bitrate should I use when converting FLAC to MP3?
320 kbps is the recommended setting for converting from lossless FLAC. This maximizes MP3 quality and is indistinguishable from the source in double-blind listening tests for most content.
Will I be able to tell the difference between the FLAC and the MP3?
At 320 kbps, most people cannot distinguish FLAC from MP3 in controlled double-blind tests. The difference is most audible on critical listening headphones with complex orchestral music.
Should I keep the original FLAC after converting?
Yes. FLAC is your lossless master. Keep it archived and use the MP3 for daily listening. Storage is cheap; re-encoding from MP3 permanently reduces quality.
Does the converter preserve FLAC metadata tags?
Standard tags (artist, album, title, track number, year) generally carry over. Check album art after converting; players read it inconsistently.
Is my file private?
Yes. The conversion runs in your browser tab and nothing is uploaded, so your files never leave your device. The only limit is size: 100 MB for this format. Bigger files route to the desktop app.
Converting a large lossless music collection?
TeraConvert Desktop encodes multi-gigabyte FLAC archives to MP3 natively with FFmpeg and no browser WASM heap limit for large audio files.
