Heads up before converting to MP3
What this specific conversion changes about your audio.
Converting WAV to MP3 discards audio data
WAV is lossless, but MP3 is lossy — this conversion permanently throws away part of the signal to save space. Keep your WAV file as the master and use the MP3 copy for sharing or playback.
Best practices for MP3
Small choices that keep your output sounding right.
- Play the first converted file before batch-converting the rest, so you catch a wrong setting early.
- For MP3, choose a bitrate that fits the use: 192–256 kbps keeps most music transparent, 320 kbps for archival-grade lossy.
When NOT to convert to MP3
Cases where a different format serves you better.
When you need an editable master
If you might re-edit or re-export later, keep the lossless WAV original and skip flattening it to MP3. Lossy targets are for delivery, not for archiving the source of truth.
