What changes in this conversion

  • AAC opens almost everywhere, so the converted file will work on devices and programs that refused the original OGG.
  • Both OGG and AAC are lossy, so re-encoding discards a little more audio detail on top of what was already lost. Converting once is fine; repeating it many times is not.

How to use

  1. Add your OGG file

    Drag the OGG file onto the drop area above, or click it to pick a file from your device. You can add several files at once.

  2. Confirm AAC as the output

    AAC is already selected as the output format on this page. You can pick the bitrate — higher keeps more of the sound, lower makes a smaller file.

  3. Run the conversion

    Press the convert button. Audio decodes and re-encodes in your browser — a normal song finishes in a few seconds.

  4. Download the AAC file

    When it finishes, download the AAC file. Converting multiple files gives you the option to download them together as a ZIP.

Frequently asked questions

Is converting OGG to AAC really free?

Yes. OGG to AAC conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.

Are my OGG files uploaded to a server?

No. The conversion runs entirely inside your browser using WebAssembly, so the OGG file never leaves your device. That is also why it works without an internet connection once the page has loaded.

Is there a file size limit for OGG to AAC conversion?

The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
