Most converter sites force you to create an account before converting. It's a growth hack, not a feature. AudioUtils skips all that. The converter works immediately.
Free users get 5 conversions per month without any account. Need more? Pro accounts exist but are never required for basic use.
Your privacy matters. No signup means no tracking profile tied to your conversions. No email list. No data to breach. FLAC is lossless. Converting to MP3 reduces file size at the cost of some audio data. Use a high bitrate to minimize loss.
Frequently Asked Questions
What MP3 bitrate should I use for FLAC conversion?
320 kbps (CBR) for archival-quality MP3 you want to sound indistinguishable from the FLAC — ideal if you're phasing out the FLAC. 256 kbps is the real sweet spot: quality is extremely close to 320 and files are ~20% smaller. 192 kbps is fine for casual listening on earbuds. Below 192 kbps, cymbals and reverb tails start to show artifacts versus the FLAC source; stay above that line for music.
How much smaller will the MP3 be?
For typical CD-source FLAC: ~80% smaller at 320 kbps, ~85% at 256 kbps, ~90% at 192 kbps. Example: a 40 MB FLAC track → 8 MB (320), 6 MB (256), 4.5 MB (192). Hi-res FLAC (24-bit / 96 kHz) shrinks even more dramatically — an 80 MB hi-res FLAC compresses to roughly the same MP3 sizes since MP3 caps at 16-bit / 48 kHz internally.
Will the conversion preserve metadata and album art?
Yes for the basics: title, artist, album, track number, year, genre, and album art transfer from FLAC's Vorbis comments to MP3's ID3v2 tags. More exotic tags (composer, conductor, BPM, ReplayGain) may or may not map cleanly depending on how the FLAC was tagged. For large library conversions, verify tags in a tool like Mp3tag or MusicBrainz Picard after conversion.
Does converting 24-bit hi-res FLAC to MP3 lose the hi-res quality?
Technically yes — MP3 is 16-bit only, and standard MP3 sample rates are 32/44.1/48 kHz. A 24-bit / 96 kHz FLAC gets downsampled and dithered to 16-bit / 48 kHz (or 44.1 kHz) during encoding. In practice, the audible difference between 24/96 FLAC and 320 kbps MP3 is negligible on almost all playback chains. Keep the FLAC for the archive, use the MP3 for mobile.
Will the MP3 work on my phone, car, and older hardware?
Yes. MP3 is the most widely supported audio codec ever made — iOS, Android, every car stereo from ~2002 onward, every smart speaker, Bluetooth headphones, DJ software, web players. The converted MP3 is standard ID3v2.3-tagged, which is the flavor almost every device reads cleanly. If you need ID3v1 for very old hardware, re-tag in a desktop tool.
Does converting FLAC to MP3 and back recover losses?
No. Once you encode FLAC→MP3, the MP3 is lossy forever. Converting that MP3 back to FLAC just wraps the already-lossy audio in a lossless container — it doesn't restore the discarded data. Always keep the original FLAC as your master. Treat MP3 as a disposable derivative.
Can I convert multiple FLAC files?
You can convert files one at a time — drop a file, convert, download, repeat. A typical 30 MB FLAC track converts in 2–4 seconds, so working through an album takes a couple of minutes.
