How to Convert VOB to MPG
Follow these simple steps to convert your file in seconds.
Choose a VOB file
Select or drop one file up to 100 MB. Its extension must match this converter. Availability is checked before transfer.

Tips for Converting VOB to MPG
Practical advice to get the best results from this conversion.
Why this conversion is worth doing
DVD Video Object has a known limitation: mPEG-2 video compression is inefficient by modern standards. MPEG Video addresses this with a key advantage: widely compatible with virtually all media players and hardware devices. Converting from VOB to MPG is most worthwhile when this specific trade-off matters for the way you intend to use the file.
Match the format to the actual workflow
DVD Video Object is most commonly used for dvd-video disc content storage and playback, while MPEG Video is the standard for dvd-video content and disc authoring. If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where VOB is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.
Watch for this limitation in the MPG output
MPEG Video has its own limitation worth understanding before you commit: significantly lower compression efficiency than modern H.264 or H.265. After the conversion completes, open the MPG file and verify that this limitation does not affect your specific use case — for some workflows it is irrelevant; for others it can be a deal-breaker.
Avoid transcoding unless necessary
Every time you transcode (re-encode) a video, some quality is lost unless you use a lossless codec. If you only need to change the container format without changing the codec, use a remux (stream copy) operation instead of a full re-encode. This preserves original quality and is much faster.
Understanding VOB and MPG Formats
Learn about the source and target file formats to understand what happens during conversion.
Source Format
DVD Video Object
video/dvdVOB (Video Object) is the container format used on DVD-Video discs, containing multiplexed MPEG-2 video, audio (AC3, DTS, or MPEG), subtitles, and navigation data. Each VOB file typically represents a portion of the DVD content, with files limited to approximately 1 GB due to the UDF filesystem used on DVDs. VOB files can include copy protection data such as CSS encryption.
Advantages
- Standard format for DVD-Video ensuring universal DVD player compatibility
- Supports multiple audio tracks, subtitle streams, and navigation menus
- Well-established format with decades of player and software support
Limitations
- MPEG-2 video compression is inefficient by modern standards
- CSS copy protection can prevent direct playback or conversion
- Limited to DVD resolution (720x480 NTSC or 720x576 PAL)
Common Uses
- DVD-Video disc content storage and playback
- DVD ripping and backup operations
- Legacy video archival from DVD collections
Target Format
MPEG Video
video/mpegMPG is a common file extension for MPEG-1 and MPEG-2 video files, standards developed by the Moving Picture Experts Group. MPEG-1 was the first widely used video compression standard (used in Video CDs), while MPEG-2 became the standard for DVD-Video and digital television broadcasting. MPG files contain multiplexed video and audio streams in a program or transport stream.
Advantages
- Widely compatible with virtually all media players and hardware devices
- MPEG-2 provides good quality suitable for DVD and broadcast content
- Simple, mature format with well-established decoder support
Limitations
- Significantly lower compression efficiency than modern H.264 or H.265
- Large file sizes for equivalent quality compared to modern codecs
- Limited metadata, subtitle, and multi-track support
Common Uses
- DVD-Video content and disc authoring
- Digital television broadcasting and cable TV distribution
- Legacy video archives and Video CD content
