Why Convert VOB to 3G2?

You have video files from a DVD and need to watch them on a mobile device. The problem: VOB files are designed for DVD players, not phones. They are large, encoded in MPEG-2, and most mobile devices cannot play them directly.

3G2 is a multimedia container format specifically designed for mobile phones, particularly CDMA-based devices. Converting VOB to 3G2 compresses your video significantly while maintaining acceptable quality for smaller screens. In our testing, a 1GB VOB file typically converts to under 100MB in 3G2 format.

How to Convert VOB to 3G2

  1. Upload your VOB file - Drag and drop or click to select your DVD video file
  2. Select 3G2 as output - The converter optimizes settings for mobile playback
  3. Download the result - Get your mobile-ready video file

The entire process runs in your browser. No software installation required, no account needed.

Understanding the Formats

VOB (Video Object)

VOB is the container format used on DVDs since 1995. Each VOB file can contain video (MPEG-2), audio (AC3, DTS, or MPEG), subtitles, and navigation data. A typical DVD movie consists of several VOB files, each up to 1GB in size due to filesystem limitations of the DVD era.

3G2 Format

3G2 (3GPP2 file format) was developed by the 3rd Generation Partnership Project 2 for CDMA-based mobile networks. Unlike the similar 3GP format used by GSM networks, 3G2 was designed for carriers like Verizon and Sprint. The format uses H.263 or H.264 video codecs with AMR or AAC audio, optimized for low bandwidth and small file sizes.

Common Use Cases

Archiving DVD Collections

Physical DVDs degrade over time. Converting your VOB files to 3G2 creates smaller backup copies you can store on a phone or tablet. While quality is reduced compared to the original, the files remain watchable on mobile screens.

Legacy Device Support

Older phones and basic feature phones often support 3G2 but struggle with larger modern formats. If you need to share video with someone using an older device, 3G2 provides maximum compatibility.

Reducing Storage Requirements

A full DVD can exceed 8GB. The same content in 3G2 format might only require 200-500MB depending on quality settings, making it practical for devices with limited storage.

Quality Considerations

3G2 was designed for small screens and limited bandwidth. Converting a DVD-quality VOB file to 3G2 involves significant compression. The video will look fine on a phone screen, but do not expect it to match the original quality on larger displays.

For better quality on modern devices, consider converting VOB to MP4 instead. MP4 offers superior compression efficiency and is supported by virtually all current smartphones and tablets.

Works in Your Browser

Our converter processes files directly in your web browser:

  • Windows, Mac, Linux, Chromebook - any desktop platform
  • Chrome, Firefox, Safari, Edge - all modern browsers
  • No software to download or install
  • Files stay on your device during processing

Pro Tip

DVDs split video across multiple VOB files (VTS_01_1.VOB, VTS_01_2.VOB, etc.). For a complete movie, convert all numbered VOB files and join them, or use the largest VOB which usually contains the main feature.

Common Mistake

Trying to convert VOB files with copy protection intact. The conversion will fail or produce corrupted output. Ensure your VOB files are from unprotected sources or properly decrypted before converting.

Best For

Transferring DVD content to older mobile phones with limited format support, or reducing file size dramatically for storage-constrained devices.

Not Recommended

Do not use 3G2 if you plan to watch on a tablet, smart TV, or computer monitor. The low resolution and heavy compression are only suitable for small phone screens. Use MP4 for better quality on larger displays.

Frequently Asked Questions

VOB (Video Object) is the container format used on DVDs. It contains MPEG-2 video, audio tracks (often AC3 or DTS), subtitles, and menu data. VOB files are typically found in the VIDEO_TS folder when you copy a DVD.

3G2 was developed for CDMA networks (Verizon, Sprint) while 3GP was created for GSM networks (AT&T, T-Mobile). Both are mobile video formats with similar capabilities, but 3G2 is more commonly associated with CDMA devices.

Yes. 3G2 uses more aggressive compression than DVD video. However, the quality loss is acceptable for viewing on small mobile screens. For larger screens or archival purposes, consider converting to MP4 instead.

Our converter processes unprotected VOB files only. Commercial DVDs typically include copy protection that must be legally removed before conversion. We process the video files you provide without bypassing any protection.

Conversion time depends on file size and your device. A 1GB VOB file typically converts in 2-5 minutes on a modern computer. Larger files or older devices will take longer.

Browser-based conversion handles files up to several gigabytes, limited primarily by your device memory. For very large DVD rips, consider splitting VOB files or converting individual chapters.

Yes. Upload multiple VOB files and convert them in batch. This is useful when a DVD splits its content across several VOB files like VTS_01_1.VOB through VTS_01_5.VOB.

Most modern smartphones can play 3G2 files, though MP4 is more commonly used today. 3G2 is particularly useful for older devices or when maximum compatibility with legacy systems is needed.

VOB uses MPEG-2 compression from the 1990s, designed for quality over file size. 3G2 uses modern codecs like H.264 that achieve similar visual quality at much smaller file sizes, especially for mobile viewing.
