How to convert VOB to OGV
To convert VOB to OGV, upload your VOB file, choose OGV as the output format and press Convert. The finished OGV file is ready to save to your phone or computer in seconds, free, with no watermark and no sign-up. Your file is deleted from our server about 30 minutes after the conversion.
This free online converter turns VOB videos into OGV files in your browser, with no software to install and no watermark. When the video and audio inside your VOB file can be placed in OGV as they are, the streams are copied without re-encoding, which is faster and keeps the original quality. Otherwise the video is re-encoded as Theora video with Vorbis audio.
Reasons to switch from VOB to OGV
- Completely open and royalty-free
- Works in Firefox and Chrome
- Supported by free-software tools
- Plays on: Firefox, Chrome, VLC and Linux players; not supported on iOS
What to expect from this conversion
- Expect a smaller file than the VOB original, because OGV compresses more efficiently.
- OGV output uses Theora, an open codec that is less efficient than H.264 or VP9, so files are bigger for the same quality.
- VOB files from commercial DVDs are usually copy-protected and cannot be converted here. Files from your own home DVDs work fine.
- The first audio track is kept. Subtitle tracks, extra audio tracks and chapters are not included in the converted file.
