DVD Files That Won't Play on Your Phone

You've ripped a DVD or copied files from the VIDEO_TS folder, but your phone can't play them. VOB files are designed for DVD players, not mobile devices. They're large, encoded in MPEG-2, and wrapped in a container format phones don't understand.

Converting to 3GP solves this instantly. 3GP was specifically designed for mobile phones-it creates tiny files that play smoothly even on older devices with limited storage. If you have VOB files from a DVD collection, 3GP is the most efficient way to get them onto a phone.

How to Convert VOB to 3GP

  1. Upload your VOB file - Select the file from your computer or drag it into the converter
  2. Choose 3GP as output - The format is optimized for mobile playback and small file sizes
  3. Download the converted file - Transfer it to your phone or share via MMS

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

Why VOB and 3GP Exist

VOB (Video Object) files are the core video format used on DVDs. They contain MPEG-2 video along with audio tracks, subtitles, and menu data. A typical DVD movie is split across multiple VOB files, each up to 1GB in size. This format was designed in 1995 when optical discs and home DVD players were the standard.

3GP was created by the 3rd Generation Partnership Project in 1998 for mobile phones. It uses efficient H.263 or H.264 video compression with AMR audio-the same codec used for voice calls. A 10-minute video that's 500MB as VOB might be just 15-20MB as 3GP.

In our testing, a 4GB DVD ripped to VOB files converted to roughly 200MB of 3GP video while keeping watchable quality on phone screens.

When 3GP Makes Sense

Feature Phones and Basic Smartphones

Older phones with limited storage and processing power handle 3GP better than any other video format. If the device was made before 2015, 3GP is likely the safest choice.

MMS Video Messages

3GP is the standard format for sending video via MMS. File size limits for MMS are typically 300KB to 1MB, and 3GP's compression makes it possible to fit short clips within these limits.

Saving Storage Space

If you want to carry dozens of DVD videos on a phone with limited memory, 3GP's tiny file sizes let you fit far more content than other formats.

3GP vs Other Mobile Formats

For modern smartphones (iPhone, Android devices from the past decade), VOB to MP4 is usually the better choice. MP4 offers higher quality at reasonable file sizes and plays on virtually every device made since 2010.

Choose 3GP when:

  • The target device is an older feature phone or basic smartphone
  • You need the smallest possible file size
  • You're sending video via MMS
  • Storage is extremely limited

Choose MP4 when:

  • You're using a modern smartphone or tablet
  • Video quality matters more than file size
  • You'll watch on a larger screen

What to Expect

3GP prioritizes file size over quality. The format was designed for 2-inch phone screens with 176x144 resolution. While our converter produces the best quality possible within 3GP's constraints, you'll notice reduced sharpness compared to the original DVD.

This is the tradeoff: a DVD scene that's crystal clear on a TV becomes a smaller, more compressed video on a phone. For handheld viewing, most people find 3GP perfectly watchable. For anything larger than a phone screen, consider VOB to MKV for maximum quality preservation.

Works on Any Device

Our 3GP converter runs entirely in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • Tablets and smartphones

Your files stay on your device throughout the conversion. Nothing gets uploaded to external servers.

Pro Tip

When ripping DVDs, extract individual VOB files rather than concatenating them. This gives you chapter-level control and makes it easier to convert specific scenes to 3GP without processing the entire movie.

Common Mistake

Converting to 3GP for playback on modern smartphones. If you have an iPhone or recent Android device, MP4 will give you much better quality at only slightly larger file sizes. 3GP is best for legacy devices or MMS.

Best For

Sending short video clips via MMS, loading videos onto older feature phones with limited storage, or archiving large DVD collections in a compact format for mobile access.

Not Recommended

Don't use 3GP if you plan to watch on anything larger than a phone screen. The low resolution and heavy compression make 3GP unsuitable for tablets, computers, or TV playback. Use MP4 or MKV instead.

Frequently Asked Questions

VOB (Video Object) is the main video format on DVDs. Found in the VIDEO_TS folder, VOB files contain MPEG-2 video, audio tracks, subtitles, and navigation data. Each file can be up to 1GB, with movies split across multiple VOB files.

3GP is a mobile video format created for cell phones in 1998. It produces extremely small files optimized for devices with limited storage and slow data connections. It's the standard format for MMS video messages.

No. 3GP uses aggressive compression to create small files. Quality will be noticeably reduced compared to the DVD original. This is acceptable for phone screens but not ideal for larger displays.

Significantly smaller. A 1GB VOB file typically converts to 30-50MB in 3GP format-roughly 95% reduction. The exact size depends on video length and complexity.

Yes, most modern Android phones can play 3GP. iPhones have limited native support but apps like VLC can play 3GP files. However, for modern phones MP4 is usually the better choice.

Use MP4 for smartphones made in the last 10 years-better quality at reasonable file sizes. Use 3GP for older feature phones, basic phones, or when you need the absolute smallest file size for MMS.

Yes. You can upload several VOB files and convert them all to 3GP in one batch. This is useful when converting an entire DVD that spans multiple VOB files.

3GP typically outputs at mobile-friendly resolutions like 176x144, 320x240, or 352x288 pixels. These lower resolutions are part of why 3GP files are so small.

No. The converter runs entirely in your web browser. Just visit the page, upload your VOB file, and download the converted 3GP. Works on any computer or device.

Yes. All conversion happens locally in your browser. Your VOB files are not uploaded to any server-they never leave your device during the conversion process.
