How to convert VOB to WEBM
To convert VOB to WEBM, upload your VOB file, choose WEBM as the output format and press Convert. The finished WEBM 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 WEBM 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 WEBM 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 VP9 video with Opus audio.
Why convert VOB to WEBM?
- Designed for the web and royalty-free
- Plays natively in Chrome, Firefox, Edge and Android
- Efficient VP9 compression
- Plays on: Chrome, Firefox, Edge, Opera, Android and VLC; partial on Safari and iOS
What to expect from this conversion
- Expect a smaller file than the VOB original, because WEBM compresses more efficiently.
- WebM uses VP9, which compresses very well but takes longer to encode than H.264, so large videos need patience.
- VOB files from commercial DVDs are usually copy-protected and cannot be converted here. Files from your own home DVDs work fine.
- VOB is a legacy format, so moving to WEBM makes the video easier to play, edit and share on current devices.
- The first audio track is kept. Subtitle tracks, extra audio tracks and chapters are not included in the converted file.
