What is WAV to MP3 Compression?
WAV files are uncompressed, storing raw audio data in massive file sizes. MP3 uses smart compression to reduce file size by 90% while maintaining perceptually similar quality. This makes audio practical for sharing, storage, and portable listening.
Our converter transforms large WAV files into space-efficient MP3 format perfect for everyday use.

Frequently Asked Questions
How much smaller will my MP3 be?
At 320kbps (highest quality), MP3 is ~90% smaller than WAV. At 128kbps, it's ~95% smaller. A 50MB WAV becomes 5MB (320kbps) or 2MB (128kbps) MP3.
Can I hear the difference between WAV and MP3?
At 320kbps, most people can't hear any difference. At 256kbps, the difference is subtle and only noticeable on high-end audio equipment. At 128kbps, differences may be audible on quality headphones.
Which bitrate should I use?
320kbps for music you care about, 256kbps for a great balance, 192kbps for casual listening, and 128kbps for voice/podcasts. Higher bitrate = better quality but larger files.
Should I keep WAV originals?
For archival purposes, yes—keep WAV as master copies. For daily listening, MP3 is practical. WAV prevents cumulative quality loss if you need to edit later.
Is WAV better quality than MP3?
WAV is uncompressed, so technically yes. But at 320kbps, MP3 is perceptually transparent—indistinguishable from WAV in blind tests for most listeners. WAV's advantage is for editing, not listening.
Are my files stored?
No. All processing is secure and files are automatically deleted after compression. We never store or access your audio.
