How to Convert Audio Files — MP3, WAV, M4A and More

Audio files come in many formats, and not all of them play everywhere. The most common problem is a WAV file that is too large to email or share, or an M4A file that won't play on a non-Apple device. Converting audio to MP3 solves both.

Common Audio Formats Explained

• MP3 — the universal standard. Plays on every device. 10× smaller than WAV.
• WAV — uncompressed, lossless audio. Huge files but best quality.
• M4A / AAC — Apple's format, similar size to MP3 but less universal.
• FLAC — lossless compression, smaller than WAV but not supported by Apple.
• OGG — open-source format, supported by most modern devices but not all.

Why Convert to MP3?

MP3 is the most compatible audio format — it plays on every phone, computer, car stereo, and media player. It is also 10× smaller than WAV, making it easy to email, share, and store. For everyday listening, the quality difference between WAV and a 192kbps MP3 is negligible.
