Frequently Asked Questions - FLAC to MP3
How much does the size reduce when converting FLAC to MP3?
Example: a 35 MB FLAC (3 min song) converts to ~3 MB MP3. Typical 90% reduction. A discography of 50 FLAC albums (80 GB) becomes 8 GB in MP3.
Do I lose audible quality?
For most people and audio equipment, no. FLAC is lossless, but MP3 with our quality options (128-320 kbps) maintains audible frequencies. Only audiophiles with high-end equipment will notice differences in critical listening, especially at higher bitrates.
When should I NOT convert FLAC to MP3?
Don't convert if: 1) You're an audiophile with high-end equipment, 2) Archiving music for long-term preservation, 3) Planning to edit/remaster audio professionally, 4) Have plenty of storage and prioritize maximum quality.
Can I reconvert MP3 to FLAC to recover quality?
No. Converting MP3 → FLAC only increases file size without recovering lost data. The resulting FLAC is a lossless copy of the MP3, not the original audio.
Why are my FLAC files never uploaded to servers?
Total privacy. Your FLAC collection (which may include demos, unreleased music, exclusive recordings) is processed 100% on your device. Not even we can see your files.
Will audiophiles notice the difference after conversion?
With high-end headphones and trained ears, possibly—subtle details like instrument separation and spatial depth may be slightly reduced at lower bitrates. However, for 95% of listeners using consumer headphones or speakers, MP3 at our quality settings (especially 320 kbps) is imperceptible from FLAC in normal listening conditions.
