How do I convert a VOB file to ASF with LetsConvert?

Upload your VOB file, select ASF as the output format, choose your preferred resolution and bitrate (or keep defaults), and click Convert. The tool re-encodes the MPEG-2 video to Windows Media Video (WMV) inside an ASF container. Once done, download your .asf file—no player-specific plugins required.

Why should I convert VOB to ASF instead of keeping the original?

VOB files from DVDs are large MPEG-2 streams that many online platforms and modern media players don't recognize. ASF/WMV compresses the video significantly, reducing file size while maintaining decent playback quality, and it runs natively in Windows Media Player, making it ideal for local streaming or legacy software.

What happens to the original video quality and audio when converting VOB to ASF?

The video track is re-encoded to WMV, so there is generational loss—you lose the original MPEG-2's exact color precision and bitrate. The audio is converted to WMA if it was AC3 or PCM; if the original VOB had multiple audio tracks, only the first one is retained by default unless you enable multi-track selection. Subtitles or chapters are not preserved in ASF and must be extracted separately.
