MP3 vs WAV vs FLAC: Which Audio Format Should You Use?
October 8, 2026
Short answer: use MP3 to share and play music anywhere, FLAC to keep a music library at full quality in a smaller file, and WAV to edit or hand audio to a studio. The most important rule is below the table: converting a lossy file to WAV or FLAC does not bring the quality back.
Convert WAV to MP3The three formats side by side
| MP3 | WAV | FLAC | |
|---|---|---|---|
| Type | Lossy (some data is thrown away) | Uncompressed | Lossless (compressed, nothing thrown away) |
| Size of one minute (CD quality) | About 1.4 MB at 192 kbps | About 10.6 MB | Roughly half of WAV or less |
| Plays on | Everything | Almost everything | Most modern players and phones, not every old device |
| Tags and cover art | Yes | Limited | Yes |
| Best for | Sharing, phones, everyday listening | Editing, recording, mastering | Archiving and high-quality listening |
The WAV figure comes from the format itself: CD-quality audio is 1,411 kbps, which is about 10.6 MB per minute. In one example comparison, a three-minute track of about 32 MB as WAV came to about 12 MB as FLAC with no quality loss. The exact saving depends on the music.
Lossy and lossless, in one paragraph
A lossless file (WAV, FLAC) keeps all the audio information, and you get back exactly what was recorded. A lossy file (MP3) removes parts of the sound that people hear least, so the file becomes much smaller. At a good bitrate the difference is very hard to hear on ordinary speakers and earphones. At low bitrates it is audible as a thin, "swishy" sound.
Which one should you pick?
- Music for your phone, car or a USB stick: MP3 at 192 kbps or more.
- Your own music collection you want to keep for years: FLAC. You can always make MP3 copies from it.
- Recording, podcast editing, or sending audio to a studio: WAV, because every editing program reads it and nothing has been compressed.
- A ringtone for iPhone: neither, you need M4R (WAV to M4R, MP3 to M4R).
The rule people get wrong
You cannot make a bad file better by converting it. If you convert an MP3 to FLAC or WAV, you get a bigger file with the same sound, because the detail was already thrown away when the MP3 was made. People do this hoping for "better quality" and end up with files several times larger for nothing.
Convert in this direction:
- WAV or FLAC to MP3 when you need a small file to share or play anywhere: WAV to MP3, FLAC to MP3.
- WAV to FLAC when you want to archive without losing anything and save space: WAV to FLAC.
- MP3 or M4A to WAV only because a program requires WAV, and you accept that quality does not improve: MP3 to WAV, M4A to MP3.
What Ident Convert does with audio
- To MP3: 192 kbps, which suits music for phones and everyday listening. Sample rate up to 48 kHz, and 5.1 surround is mixed down to stereo.
- To WAV: 16-bit. To FLAC: keeps up to 24-bit, so high-resolution files stay high-resolution.
- Tags: the title and artist are carried over where the target format supports them. Cover art is not.
- Errors: a damaged or wrong file gets a clear message instead of a stack of technical text.
Files up to 300 MB are accepted.
Frequently asked questions
Is FLAC better than MP3?
FLAC keeps everything, and an MP3 does not, so in that sense yes. But for casual listening on phone speakers or earphones most people cannot tell a good MP3 from a FLAC. The real trade is file size against compatibility.
Is WAV better than FLAC?
The sound is identical, because both are lossless. WAV is larger and has weaker tag support, but every editing program reads it. FLAC is smaller and fine for listening.
What bitrate should I use for MP3?
192 kbps is a sensible default for music. 128 kbps is fine for speech and podcasts, and 256 to 320 kbps is for people who want to be careful.
Are my audio files kept after converting?
No. Files are processed for the conversion and removed afterward. The Privacy Policy has the exact details.
