Why Convert WAV to MP3?
WAV files store uncompressed raw audio data, making them impractically large for everyday storage, streaming, and sharing.
A three-minute WAV file is 30-50 MB; the same audio as MP3 at 320 kbps is under 8 MB with no audible difference on standard playback systems.

Frequently Asked Questions
What MP3 bitrate should I choose?
320 kbps is the highest standard MP3 bitrate and is indistinguishable from the source WAV in double-blind tests on typical speakers and headphones. 192 kbps is sufficient for casual listening.
Will I lose audio quality converting WAV to MP3?
MP3 encoding is lossy and discards audio data that psychoacoustic models consider least perceptible. At 320 kbps, most listeners cannot distinguish the output from the original WAV.
Can I keep the original WAV for archiving?
Yes. Always archive your original WAV files. MP3 compression is irreversible, and you may need the lossless WAV for future editing, remixing, or format conversion.
Is the metadata (artist, title, album) preserved?
WAV files rarely carry tags, so there is usually nothing to bring over. Add ID3 tags to the MP3 in your music app afterwards.
Is my file private?
Yes. The conversion runs in your browser tab and nothing is uploaded, so your files never leave your device. The only limit is size: 100 MB for this format. Bigger files route to the desktop app.
Encoding a large WAV audio archive?
TeraConvert Desktop encodes multi-gigabyte WAV files to MP3 using FFmpeg natively with no browser WASM heap constraints.
