FAQ
Frequently asked questions
How do I convert MP3 to M4A?
Drop your MP3 files onto the page and click Convert. Each file is re-encoded to M4A in your browser and gets its own Download button.
Is my audio uploaded to a server?
No. Conversion runs entirely in your browser with a WebAssembly build of FFmpeg, so your files never leave your device.
Why convert MP3 to M4A?
M4A (AAC) is the native audio format on iPhone, iPad, Mac, and iTunes, with better quality than MP3 at the same bitrate.
Will I lose audio quality?
M4A is a compressed format, so re-encoding involves a small quality change. Files are encoded at a high quality setting to keep this as minimal as possible.
Can I convert several MP3 files at once?
Yes. Drop in as many as you like and they all convert in one pass, each with its own download.
Is this converter free?
Yes. It is free to use with no sign-up, no account, and no watermark on your files.
