MP3 to M4A: Save Storage Without Noticeable Quality Loss

Overview

If your library is full of MP3s, converting to M4A (AAC) can reduce file size at the same perceived quality. It is a simple way to free up storage without changing how your music sounds.

Why M4A Is Smaller

AAC (inside M4A) is more efficient than MP3. At the same bitrate, it usually sounds clearer, which lets you use a lower bitrate for similar quality.

Who Should Convert?

• People with limited storage
• Mobile users who stream on cellular
• Anyone sharing audio online

Suggested Settings

• Voice: 96–128 kbps M4A
• Music: 128–192 kbps M4A
• Sample rate: Keep original
