• 320 kbps — Maximum MP3 quality

Tips

1. WAV → MP3 for sharing — WAV files are 10x larger than MP3. Convert before sending
2. Keep FLAC for archiving — FLAC is lossless and 50% smaller than WAV. Perfect for music libraries
3. Use 192 kbps for music — Most listeners can't tell the difference from 320 kbps
4. M4A from iPhone — Convert to MP3 with M4A to MP3 for universal compatibility
5. Extract from video first — Use MP4 to MP3 to get audio from videos, then convert to your preferred format

Frequently Asked Questions

Does converting audio lose quality?

Converting to lossy formats (MP3, AAC, OGG) involves some quality loss. Converting to lossless (FLAC, WAV) preserves quality but can't restore quality lost in the source.

What bitrate should I use for MP3?

192 kbps is ideal for most uses. Use 320 kbps for critical listening, 128 kbps for speech-only content.

Is it free?
