What changes in this conversion

  • AAC uses lossy compression, so some audio detail is discarded permanently in exchange for a much smaller file.
  • AAC opens almost everywhere, so the converted file will work on devices and programs that refused the original MOV.
  • Only the audio track is kept — the video picture is discarded, so the result is far smaller than the original MOV file.

How to use

  1. Add your MOV file

    Drag the MOV 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. Video is re-encoded frame by frame on your own machine, so a long clip can take several minutes. The tab has to stay open.

  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 MOV to AAC really free?

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

Are my MOV files uploaded to a server?

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

Does converting MOV to AAC reduce quality?

AAC uses lossy compression, so some detail is discarded. At high quality settings the difference is usually invisible, and the file becomes far smaller.

Does the picture disappear when I convert MOV to AAC?

Yes — AAC is an audio format, so only the soundtrack is extracted. The video track is dropped, which is usually the point when you want just the audio.

Is there a file size limit for MOV 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.
