    About VOB and AAC

    VOB: VOB files are the video files on a DVD disc (inside the VIDEO_TS folder).

    AAC: AAC is the successor to MP3 and the audio codec behind YouTube, iTunes and most streaming services. A .aac file stores the raw AAC stream without an MP4 wrapper.

    Frequently asked questions

    How do I convert VOB to AAC on my phone?
    Open this page in your phone's browser (Safari, Chrome, Samsung Internet), tap Choose files, pick your VOB, make sure AAC is selected and tap Convert. The AAC file is saved to your Downloads.
    Will converting VOB to AAC reduce quality?
    Only the sound is kept — the picture is dropped, so the AAC file is far smaller than the VOB video.
