VOB is a DVD-Video program-stream file that may carry MPEG-2 video, several audio tracks, subtitles, and navigation packets.
What this converter actually supports
Convertr uses the deployed FFmpeg toolchain for published audio and video routes. A container such as MP4, MOV, MKV, AVI, or WebM can hold different codecs, so the file extension alone does not guarantee that a particular player will accept the contents.
Convert a VOB title to MP4 for playback while retaining the DVD structure if menus and chapters matter.
The public upload limit is 1 GB. Convertr does not reduce dimensions, duration, resolution, or output quality merely to manage worker load.
Quality and format limits
Keep the original dimensions and frame rate unless you intentionally need a smaller result. Remuxing compatible streams avoids re-encoding; changing codecs is lossy, so repeated conversions should be avoided.
Encrypted discs are unsupported, and one VOB may be only part of a title split across several files.
Published VOB inputs

Published VOB outputs
Choose one of these implemented routes; a listed extension is not a promise that every codec variant will decode.
Check that the file opens in its original application, is not encrypted or DRM-protected, and really matches its extension. A damaged header, unsupported internal codec, missing linked asset, or mislabeled file can fail even when VOB is generally supported. Try a different published target only when it fits your goal; changing the extension by hand does not convert the file.
