How to choose between MP3 and WAV

Pick based on destination

The best format is often the one that fits where your file is going next: a browser, a phone, an editor, a web page, or a backup.

Think about trade-offs

Most comparisons come down to size versus quality, editing flexibility versus portability, or modern efficiency versus broader compatibility.

Convert only when needed

If the original file already fits the workflow, keep it. Convert when you need a better match for compatibility or delivery.
