FLAC vs MP3
FLAC (Free Lossless Audio Codec) compresses audio without losing anything — like a ZIP file for sound. It’s the format of choice for CD rips, high-resolution downloads and audiophile libraries. The price is size: typically half to two-thirds of an uncompressed WAV, and several times larger than an MP3.
MP3 discards details the ear is least sensitive to, which makes files far smaller and compatible with everything: phones, car stereos, old MP3 players, smart speakers, DJ software and game consoles.
| FLAC | MP3 (320 kbps) | |
|---|---|---|
| Compression | Lossless | Lossy |
| 4-minute song | ≈ 20–40 MB | ≈ 10 MB |
| Plays everywhere | Not always | Yes |
| Best for | Archiving, hi-fi listening | Phones, cars, everyday use |
When to convert
- Your phone or player is full. Keep FLAC at home and carry MP3s.
- Your car or older device doesn’t read FLAC. Many car stereos and USB players only accept MP3.
- Sharing a track by email or messaging, where a 30 MB file is impractical.
- DJ or video software that works better with MP3.
Which bitrate for which listener?
- 320 kbps — headphones, a good hi-fi system, or if you simply want the best MP3 possible. About 2.4 MB per minute.
- 256 kbps — near-transparent for most people and most music, noticeably smaller.
- 192 kbps — a good everyday choice for phones, cars and earbuds, where background noise masks small differences.
- 128 kbps — only for spoken word or when storage is extremely tight.
A whole 50-minute album at 320 kbps takes about 120 MB, compared with roughly 250–400 MB in FLAC.
Tips
- Always keep your FLAC files: you can create new MP3s at any bitrate later, but you can’t recover lossless audio from an MP3.
- For editing, convert FLAC to WAV instead with the audio converter.
- Coming from other formats? See WAV to MP3 and M4A to MP3.
