M4A to MP3
Drop an M4A or AAC file — Voice Memos, songs, podcast clips. We re-encode it as MP3 right here in your tab. The original never leaves your device.

or click to pick. AAC files also supported.
How it works
Your browser already decodes audio. We pair that with a tiny encoder (pure JavaScript for MP3, or a slim WebAssembly codec for less common formats) and put it behind a drop target. The whole pipeline runs in your tab. The first conversion may take a moment to load the codec; after that it's instant and cached.
Why convert M4A files
M4A files are great for some workflows and frustrating for others. MP3 fixes the common compatibility headaches without losing what matters about your audio.
