MP3 vs WAV: Which Audio Format Should You Use?

Choosing between MP3 and WAV depends on what you're doing with the audio. Here's a quick breakdown.

MP3 — compressed, small, universal

MP3 compresses audio by removing frequencies the human ear barely notices. The result is a file 5–10× smaller than WAV with very good quality for casual listening, podcasts, and streaming.

WAV — uncompressed, large, lossless

WAV stores every bit of the original audio. It's the format of choice for music production, audio editing, and archiving because there's zero quality loss. The downside: file sizes are much larger.

When to use which

• Use MP3 for streaming, sharing, podcasts, and background music.
• Use WAV for recording, editing, mastering, and archiving.
