MP3 (MPEG Audio Layer 3) is the most widely supported lossy audio format in the world. It achieves small file sizes by using perceptual coding to discard audio data that human ears can't easily detect.
MP3 files are compact (typically 3–5 MB per song) and play on every device, but the lossy compression means some audio detail is permanently removed during encoding.
WAV (Waveform Audio File Format) stores uncompressed PCM audio — raw audio data with no compression or quality loss. It's the standard format for professional audio editing, CD mastering, and music production.
WAV files are much larger than MP3 (roughly 10x), but they're universally compatible with audio editing software and avoid any additional compression artifacts during processing.
| Feature | MP3 | WAV |
|---|---|---|
| Compression | Lossy | None (uncompressed PCM) |
| Audio quality | Good at high bitrates | Perfect (lossless) |
| File size (4 min song) | ~4–5 MB | ~40 MB |
| Editing suitability | Poor (re-encoding degrades quality) | Excellent (no quality loss) |
| CD burning | Requires conversion | Native CD audio format |
| DAW compatibility | Supported but not ideal | Universal standard |
| Metadata | Full ID3 tags | Limited |
| Best for | Listening, sharing, streaming | Editing, mastering, archival |
DAWs (Digital Audio Workstations) like Audacity, Adobe Audition, Pro Tools, and FL Studio work best with uncompressed WAV. Editing MP3 directly causes quality degradation each time the file is re-encoded.
Audio CDs use uncompressed PCM audio (the same format as WAV). Converting MP3 to WAV before burning ensures proper CD compatibility without your burning software having to decode on the fly.
If you need to convert audio to another format later, starting from WAV avoids the quality loss of transcoding between two lossy formats. WAV serves as a better intermediate format.
Some professional audio equipment, broadcasting systems, and older hardware require WAV input. Converting your MP3 files ensures compatibility with these systems.
