Convert aac audio files

Advanced Audio Coding. What iTunes, YouTube and most streaming use. A series of MPEG-4 audio frames, each carrying a window of transformed, quantised spectral data. That is the format you end up with when something needs to look the same on every screen, which is why it keeps turning up in a recording from an iphone that will not play in older software. From here it can become WAV, and the conversion runs on your own device, so the file is never uploaded anywhere. The remaining 1 conversion is next in the queue and will be free.

    About the format

    Advanced Audio Coding.

    A series of MPEG-4 audio frames, each carrying a window of transformed, quantised spectral data.

    Where it is good
    • Better quality than MP3 at the same bitrate
    • The native format of iPhones, iPads and the Apple ecosystem
    • Works with the same .m4a container as video
    Where it falls short
    • Slightly less support on old desktop software
    • Still lossy
    • Can carry DRM in the commercial ecosystem
    You will find it on
    Apple devices, YouTube, podcasts, streaming services

    The thing people miss

    The extension .m4a and the codec AAC are not the same thing — .m4a is the container, and that container can hold other codecs too.

    How to

    Converting a AAC file

    1. 01

      Add your aac audio

      Drag the file onto the drop zone, or tap to browse. Only one file is needed.

    2. 02

      Pick what you want it to become

      Every format this file can become is listed in the switchboard. Pick one and the converter opens with sensible defaults already set.

    3. 03

      Download the result

      Your converted file downloads straight to your device. Nothing was uploaded, so there is no file to delete from a server afterwards.

    Questions

    AAC conversion questions

    How do I convert AAC to another format?

    Add your aac audio file to the drop zone, choose the target format, adjust the options if you want to, and press convert. The finished file downloads immediately.

    Is my file uploaded anywhere?

    For most conversions, no. They run entirely inside your browser tab. The file is read from your device and the result is written back to your device.

    Do I need an account?

    No. There is no signup step, no email capture and no usage counter. Open the tool, convert the file, close the tab.

    Will there be a watermark or a page limit?

    Neither. On-device conversions produce a clean file with no branding and no cap on pages, size or number of files.
