02

Choose an output format

Pick from over a hundred output formats. Filter by category or search by name - every option is open to everyone, no account needed.

03

Convert & download

Hit Convert and grab your download link moments later. Originals are erased when the job completes; results are cleared within about an hour.

What is a VOB file?

The VOB (DVD-Video Object) format is a container format used in DVD-Video media, strictly compliant with the MPEG-2 Program Stream standard (ISO/IEC 13818-1). Located within the VIDEO_TS directory of a DVD, a VOB file multiplexes MPEG-2 video streams, audio streams (formats including Linear PCM, AC-3, or DTS), and subtitle streams (subpictures) into a single datastream. The format supports copy protection via the Content Scramble System (CSS) and functions as the core delivery mechanism for standard-definition digital video on optical discs.

How to open a VOB file

VOB files are natively supported by standalone DVD players and computer software designed for DVD playback, such as CyberLink PowerDVD. On standard operating systems without dedicated DVD software, the format can be opened using the VLC media player, GOM Player, or MPC-HC, which contain the necessary MPEG-2 decoders. Users may need to open the associated IFO files to navigate menus properly rather than playing raw VOB segments.

What is a WebM file?

WebM is an open, royalty-free audiovisual media file format sponsored by Google, derived from the Matroska (MKV) container. Designed specifically for the HTML5 video element, it restricts streams to specific codecs: video is compressed using VP8, VP9, or AV1, while audio utilizes Vorbis or Opus. The format structure is defined by a subset of the Matroska specifications, prioritizing efficiency for web streaming and low computational overhead for decoding in browser environments.

How to open a WebM file

As a native HTML5 format, WebM files open directly in modern web browsers including Google Chrome, Mozilla Firefox, Microsoft Edge, and Opera without plugins. For offline playback, cross-platform media players like VLC media player, MPV, and FFmpeg-based tools provide full support. Windows Media Player may require the installation of WebM Media Foundation Components to render these files.
