Why Convert WAV to MP3?
WAV files are uncompressed and massive — a 5-minute song can be over 50MB. While this is ideal for professional audio work, it's impractical for sharing, streaming, uploading, or storing large music libraries. MP3 compresses the same audio to about one-tenth the size.
MP3 is the most widely supported audio format for casual listening. Every music player, phone, car stereo, streaming service, and web browser handles MP3 natively. Converting your WAV to MP3 makes your audio instantly portable and shareable.
Common scenarios: sharing recordings via email or messaging apps, uploading podcasts to hosting platforms, distributing music demos or tracks, creating audio for web pages, and reducing storage usage for large audio collections.
WAV vs MP3: When to Choose MP3
Understanding when MP3 is the better choice:
| Attribute | WAV | MP3 |
|---|---|---|
| File Size | ~10MB per minute | ~1MB per minute (at 128kbps) |
| Quality | Perfect — uncompressed PCM | Very good at 192kbps+, acceptable at 128kbps |
| Sharing | Too large for email/messaging | Compact and easy to share |
| Streaming | Requires high bandwidth | Streams efficiently on any connection |
| Device Support | Universal but large | Universal and compact |
Keep WAV for archiving and editing. Convert to MP3 for distribution, sharing, and everyday listening. At 192kbps or higher, most listeners cannot distinguish MP3 from WAV.
Your Audio Stays Private
The WAV-to-MP3 conversion runs entirely in your web browser using FFmpeg WebAssembly. Your audio file is never uploaded to any server. Whether it's a voice memo, podcast recording, or music track, your content stays completely private on your device.
Frequently Asked Questions
We use 192kbps by default, which provides excellent quality for most audio. This is considered transparent quality — most listeners can't tell the difference from the original WAV. At this bitrate, a 5-minute song is about 7MB.
