What Is a WAV File?
A WAV file is uncompressed, lossless audio — the studio-quality standard. Here's what WAV is, when to use it, its trade-offs, and how to convert it.

A WAV file (Waveform Audio File Format, .wav) is uncompressed, lossless audio — a complete, bit-for-bit recording of sound with nothing thrown away. It's the format studios, editors, and CD masters use when quality matters more than file size. Microsoft and IBM introduced it in 1991, and it's been the Windows standard for raw audio ever since.
What "Uncompressed and Lossless" Means
Most audio you stream is lossy (MP3, AAC, OGG): to shrink the file, the encoder permanently discards sound it judges you won't miss. WAV does the opposite — it stores the full PCM (pulse-code modulation) data exactly as captured. Nothing is estimated or removed, so a WAV is an exact copy of the source audio. That's why it's called lossless, and why it's the reference other formats are measured against.
The trade-off is size. A typical CD-quality WAV (16-bit, 44.1kHz, stereo) uses about 10 MB per minute — roughly 1,411 kbps. A 3-minute song is ~30 MB, versus ~7 MB for a 320kbps MP3. Higher settings (24-bit, 96kHz) are even larger.
WAV File Size at a Glance
| Audio | Bitrate | Size per minute | 3-min song |
|---|---|---|---|
| WAV 16-bit / 44.1kHz (CD quality) | ~1,411 kbps | ~10 MB | ~30 MB |
| WAV 24-bit / 96kHz (hi-res) | ~4,608 kbps | ~33 MB | ~99 MB |
| FLAC (lossless, compressed) | ~800–1,000 kbps | ~6–7 MB | ~20 MB |
| MP3 320kbps (lossy) | 320 kbps | ~2.4 MB | ~7 MB |
When to Use WAV
- Audio editing and production. DAWs (Audacity, Ableton, Logic, Pro Tools) work best on uncompressed audio — no decode step, no generational loss when you re-save.
- Mastering and archiving. Keep a WAV master and export MP3/AAC copies from it; the master never degrades.
- CD burning. Audio CDs are essentially WAV-quality PCM, so WAV is the ideal source.
- Short samples, loops, sound effects, voiceovers. Small enough at short durations, and universally accepted by production software.
When NOT to Use WAV
- Phones, streaming, and everyday listening. WAV files are huge and often carry no standard metadata (no reliable title/artist/artwork tags), so a music library of WAVs is unwieldy. Use MP3 320kbps or AAC for that.
- Sharing over email or chat. A few minutes of WAV can blow past attachment limits. Convert to MP3 first, or compress.
- Long-term storage where space matters. FLAC gives you the same lossless quality at roughly a third of the size — it's the better archive format for most people.
WAV vs the Other Formats (Quick Take)
- WAV vs MP3 — WAV is lossless and huge; MP3 is lossy and tiny. Edit in WAV, listen in MP3. Full comparison →
- WAV vs FLAC — both lossless and identical in quality; FLAC is compressed (smaller) and tags better; WAV is uncompressed and slightly more compatible with older editors. Full comparison →
- WAV vs AIFF — essentially the same idea (uncompressed PCM); AIFF is Apple's version, WAV is Microsoft's. Full comparison →
- Is WAV lossless? Yes — completely. Here's why →
How to Convert WAV Files
You rarely keep audio in WAV for listening — you convert it. Common jobs, all free here:
- WAV → MP3 for a small, universal file that plays anywhere. WAV to MP3 →
- MP3 → WAV to bring audio into an editor. (Note: this makes a lossless container, but can't restore quality the MP3 already lost.) MP3 to WAV →
- WAV → FLAC to keep lossless quality at a smaller size. WAV to FLAC →
- FLAC / M4A / OGG → WAV for editing. FLAC to WAV → · M4A to WAV → · OGG to WAV →
- YouTube → WAV to pull audio from a video. YouTube to WAV →
The Honest Note on Quality
Converting to WAV never improves audio — it only stops adding further loss. A WAV made from a 128kbps MP3 is a big file that still sounds like 128kbps. WAV shines when the source is high quality (a lossless master, a CD rip, a raw recording). Start from the best source you have.

Frequently Asked Questions
What is a WAV file?
An uncompressed, lossless audio format (.wav) that stores the full PCM waveform with no quality loss — the standard for editing, mastering, and CD-quality audio.
Is a WAV file good quality?
Yes — it's the highest, lossless quality (an exact copy of the source). Nothing standard sounds better; formats like MP3 are compressed versions of WAV-quality audio.
Why are WAV files so big?
Because they're uncompressed — about 10 MB per minute at CD quality (~1,411 kbps), versus ~2.4 MB for a 320kbps MP3.
Should I use WAV or MP3?
Edit and archive in WAV; listen and share in MP3. WAV for quality and production, MP3 for size and portability.
How do I make a WAV file smaller?
Convert it to FLAC (lossless, ~1/3 the size) or to MP3 320kbps (lossy, ~1/4). See our compress guide.
Do WAV files store tags and album art?
Not reliably — WAV's metadata support is limited and inconsistent across players. If you need tags and artwork, use MP3, FLAC, or M4A.
