Why can't my car stereo play FLAC files?

Most car stereos were designed before FLAC became popular. They support MP3 and WMA universally, and some newer models add AAC, FLAC, or WAV. If your stereo only shows MP3/WMA, converting FLAC to MP3 is the fix.

Will I lose audio quality converting FLAC to MP3?

Yes — FLAC is lossless, MP3 is lossy. However, at 192 kbps the perceptual quality is excellent. On consumer headphones and car stereos, the difference is inaudible. Professional listening equipment or treated studio rooms may reveal subtle differences.

What bitrate is used for the MP3?

192 kbps CBR. This is the standard audiophile-acceptable MP3 bitrate. For maximum quality at larger file size, use WAV as output instead, which preserves the full FLAC fidelity.

Are my music files uploaded to a server?

No. FFmpeg.wasm runs entirely in your browser. Your FLAC files never leave your device.

Does Spotify or Apple Music accept FLAC files?

Neither Spotify nor Apple Music accept direct FLAC uploads from users. Apple Music uses AAC internally; Spotify uses OGG Vorbis. Converting FLAC to MP3 makes your tracks compatible with most upload portals.

Can I convert a full FLAC album at once?

Yes — up to 20 files per batch. Drop the entire album folder and download the converted MP3s as a ZIP.

Why is FLAC so much larger than MP3?

FLAC is lossless — it stores audio data perfectly with compression, but no audio data is discarded. A CD-quality FLAC is ~5× larger than a 192 kbps MP3 for the same song.

Does the converter preserve metadata (title, artist, album)?

ID3 metadata embedded in FLAC files may be partially preserved in the MP3 output, but full metadata migration is not guaranteed. Check the output in a media player after conversion.
