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 at 128 kbps maintains audible frequencies. Only audiophiles with high-end equipment will notice differences in critical listening.
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.
Does it work on iPhone and Android?
Yes, PrivAudio works on all mobile devices with a modern browser. Just open the web and convert your FLAC files without installing apps.
