WAV files are uncompressed, resulting in very large file sizes (10MB per minute). MP3 uses lossy compression to reduce file size by 90% while maintaining good audio quality. This makes files easier to share, store, and stream online.

Typical compression ratios are 10:1 to 12:1. A 50MB WAV file becomes approximately 4-5MB as MP3. At 320kbps (Best quality), a 1-minute WAV (10MB) compresses to about 2.4MB. At 128kbps (Smaller), it becomes about 1MB.

Yes, MP3 is a lossy format that discards some audio data to achieve compression. However, at high bitrates (256-320kbps), the difference is nearly imperceptible to most listeners. Choose 'Best' or 'High' quality for music where fidelity matters.

Keep WAV files for professional audio editing, archiving master recordings, or when you need lossless quality. WAV preserves all original audio data without compression. Convert to MP3 only for distribution, sharing, or when storage space is limited.

For music, use 320kbps (Best) or 256kbps (High) for excellent quality. For speech, podcasts, or audiobooks, 128kbps (Smaller) or 192kbps (Good) is sufficient. Higher bitrates preserve more detail but result in larger files.

Yes. Artist, album, title, and other ID3 tags from the WAV file are preserved during conversion. The output MP3 file will include all the same metadata as the original.

320kbps captures more audio detail and sounds closer to the original WAV, but creates larger files. 128kbps is more compressed with noticeable quality loss in complex music but works fine for speech. The difference is most apparent with headphones and high-quality audio.

Currently, this tool processes one file at a time for optimal browser performance. For batch conversion, process files sequentially. Each conversion maintains your selected quality settings.

Very fast—a typical 4-minute song converts in seconds. The speed depends on your device: modern computers convert almost instantly, while phones and tablets may take a bit longer.

No. All processing happens entirely in your browser using FFmpeg WebAssembly. Your audio files never leave your device, ensuring complete privacy and security.
