How to convert MP3 to AAC

  1. Add your MP3 file

    Drop it into the box above or click to browse. It stays on your device — nothing is uploaded.

  2. Confirm AAC as the output

    The target format is preselected; switch it if you need a different one.

  3. Convert

    The conversion runs locally in your browser. How long it takes depends on the file's size and your device.

  4. Download your AAC file

    Save the result straight to your device. We never keep a copy, because we never receive one.

Frequently asked questions

Is the MP3 to AAC converter free?
Yes. Conversions are free, with files up to 100 MB on the free plan (Pro raises this to 1 GB). There is no watermark and no sign-up.
Is my MP3 file uploaded to a server?
No. The MP3-to-AAC conversion happens entirely in your browser. Your file is processed in memory on your device and never sent anywhere.
How long does the conversion take?
Small images and documents are usually done in seconds. Large files, and long videos in particular, take longer because your own device does the work; a progress bar keeps you posted.
Do I need to install anything?
No installs and no extensions — everything runs in the page you're on, on desktop and mobile.
