DVD Videos That Won't Play Online?

VOB files are the video format stored on DVDs - they contain your movie content, audio tracks, and subtitles. The problem is that web browsers and modern streaming platforms don't support VOB playback. You can't embed a VOB file on a website or share it online without conversion.

WEBM is the solution. Developed specifically for web use, WEBM files play natively in Chrome, Firefox, Edge, and Safari. They're the standard for HTML5 video and work on every modern device without plugins or special software.

How to Convert VOB to WEBM

  1. Upload your VOB file - Drag and drop or browse to select your DVD video file
  2. Confirm WEBM output - WEBM is pre-selected for optimal web compatibility
  3. Download your video - Get your web-ready file in moments

No software installation required. The entire conversion happens in your browser, and your files stay private.

Why VOB Files Need Converting

VOB (Video Object) is a container format from the DVD era, based on MPEG-2 encoding from the 1990s. While DVDs remain common, the format has significant limitations for modern use:

  • No browser support - Web browsers cannot play VOB files directly
  • Large file sizes - DVD video uses less efficient compression than modern codecs
  • Limited streaming - VOB wasn't designed for internet delivery
  • Device incompatibility - Smartphones and tablets typically can't play VOB

In our testing, a typical 1GB VOB file converts to around 200-300MB in WEBM while maintaining visual quality. That's significant savings for web hosting and faster loading for viewers.

WEBM: Built for the Web

WEBM was developed by Google specifically for web video delivery. It uses VP8 or VP9 video codecs paired with Vorbis or Opus audio - all royalty-free and open source. This matters because:

  • Universal browser support - Works in all major browsers without plugins
  • Efficient compression - Smaller files with comparable quality to H.264
  • HTML5 native - Embed directly in web pages with simple video tags
  • Low resource usage - Optimized for streaming on mobile devices

For anyone publishing video content online, WEBM is the practical choice. It's what YouTube uses internally alongside MP4.

Common Use Cases

Digitizing DVD Collections

Have a collection of home movies or personal recordings on DVD? Converting VOB to WEBM lets you upload them to your own website, share via cloud storage, or preserve them in a future-proof format.

Web Development Projects

Building a website that needs video content from DVD sources? WEBM gives you native HTML5 compatibility without licensing concerns. Add videos to your site with a simple video tag.

Educational Content

Converting training videos or educational DVDs for online learning platforms? WEBM's efficient compression means faster uploads and smoother streaming for students on varying connection speeds.

VOB vs WEBM: Technical Comparison

Understanding the differences helps you know what to expect from conversion:

  • Codec - VOB uses MPEG-2 video; WEBM uses VP8/VP9
  • Audio - VOB contains AC-3 or MPEG audio; WEBM uses Vorbis or Opus
  • Compression - WEBM typically achieves 50-70% smaller file sizes at equivalent quality
  • Container - VOB is DVD-specific; WEBM is web-optimized
  • DRM - Commercial DVDs often have copy protection; WEBM is open format

Note: If your VOB files are from commercial DVDs with copy protection, you'll need to work with unprotected content for conversion.

Alternative Formats to Consider

While WEBM is excellent for web use, other formats might suit specific needs:

  • VOB to MP4 - Best for maximum device compatibility including iOS devices
  • VOB to MKV - Ideal for archiving with multiple audio tracks and subtitles preserved
  • VOB to MOV - Preferred for Apple ecosystem and Final Cut Pro editing

Choose WEBM when web delivery is your primary goal. For offline viewing or editing, MP4 or MKV may be more versatile.

Works on Any Device

Our converter runs entirely in your browser - no downloads or installations needed:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • iPhone, iPad, Android devices

Access the converter from any device with a modern browser. Your VOB files are processed locally, keeping your content private.

Pro Tip

When converting DVDs with multiple VOB files, check the VIDEO_TS folder for the VTS files - they're typically numbered sequentially. VTS_01_1.VOB through VTS_01_x.VOB usually contain the main feature, while smaller numbered sets are often extras or menus.

Common Mistake

Trying to convert copy-protected commercial DVDs directly. CSS encryption on retail DVDs must be removed first with appropriate tools before the VOB content can be converted.

Best For

Publishing DVD content on websites, creating HTML5 video for web applications, or uploading personal DVD recordings to streaming platforms that accept WEBM.

Not Recommended

Skip WEBM if you need maximum iOS compatibility - Apple devices work better with MP4. Also consider MP4 or MKV if you need to preserve multiple audio tracks or subtitle streams from the original DVD.

Frequently Asked Questions

VOB (Video Object) is the container format used on DVDs to store video, audio, subtitles, and menu data. VOB files are typically found in the VIDEO_TS folder of a DVD and use MPEG-2 video compression.

WEBM is designed specifically for web use. Unlike VOB files, WEBM plays natively in all modern browsers without plugins, uses more efficient compression for smaller file sizes, and is the standard format for HTML5 video embedding.

WEBM uses modern VP8/VP9 codecs that maintain good visual quality while reducing file size. For most web viewing purposes, the quality difference is negligible. In our testing, viewers typically cannot distinguish between source and converted video at normal viewing distances.

Conversion time depends on file size and your device's processing power. A typical 1GB VOB file takes 2-5 minutes on modern computers. Longer videos or older devices will take more time.

Our converter works with unprotected VOB files. Commercial DVDs often have copy protection (CSS encryption) that must be handled separately. Personal recordings and unprotected content convert without issues.

Both are modern video formats suitable for web use. WEBM uses royalty-free VP8/VP9 codecs and is optimized for web streaming. MP4 uses H.264 (licensed) and has broader device support including iOS. WEBM typically offers better compression for web delivery.

No installation required. The converter runs entirely in your web browser. Just upload your VOB file and download the WEBM result. Works on any operating system with a modern browser.

Yes. DVDs often split content across multiple VOB files (VTS_01_1.VOB, VTS_01_2.VOB, etc.). You can convert each file individually or upload them for batch processing.

Yes. Conversion happens locally in your browser. Your video files are not uploaded to external servers, ensuring your content remains private throughout the process.

All major modern browsers support WEBM: Chrome, Firefox, Edge, Safari, and Opera. This covers over 95% of web users, making WEBM a reliable choice for web video.
