Why Convert MPEG to 3G2?

MPEG files are great for computers and modern devices, but older mobile phones—especially CDMA-based devices—need a specific format to play video. The 3G2 format was designed exactly for this purpose.

Converting MPEG files to 3G2 reduces file size significantly while maintaining acceptable video quality for small screens. In our testing, 3G2 files were typically 60-70% smaller than the original MPEG, making them easier to transfer and store on phones with limited memory.

How to Convert MPEG to 3G2

  1. Upload your MPEG file - Drag and drop or click to select your video
  2. Choose 3G2 as output - Select the 3G2 format optimized for mobile playback
  3. Download your video - Get your mobile-ready file instantly

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

MPEG vs 3G2: Technical Comparison

Understanding the differences between these formats helps you know what to expect:

  • Container format - MPEG uses the MPEG-1/MPEG-2 container, while 3G2 is based on the ISO base media file format
  • Video codec - MPEG typically uses MPEG-1/2 compression; 3G2 uses H.264 or MPEG-4
  • Audio codec - MPEG uses MP2 audio; 3G2 supports EVRC, QCELP, and other mobile-optimized codecs
  • File size - 3G2 produces much smaller files, ideal for limited storage
  • Quality - Resolution is reduced for mobile screens, but clarity remains good for small displays

The 3G2 format was specifically developed by the Third Generation Partnership Project 2 (3GPP2) for CDMA mobile networks, making it the standard for certain carriers and devices.

When to Use 3G2 Format

CDMA Phone Compatibility

If you have an older CDMA-based phone (common with carriers like Verizon and Sprint in the US), 3G2 is often the only video format that works reliably.

Sending Videos via MMS

The small file size of 3G2 makes it ideal for sending video clips through multimedia messaging. Many carriers still have strict file size limits for MMS.

Limited Device Storage

Devices with minimal internal storage benefit from the compact 3G2 format. Store more videos in less space.

Alternatives to Consider

Depending on your needs, other formats might work better:

  • MPEG to 3GP - Similar to 3G2, but designed for GSM networks. Use if your device is GSM-based
  • MPEG to MP4 - Better for modern smartphones and tablets that support wider format range
  • Keep MPEG - If you're only viewing on computers, MPEG works fine without conversion

For the widest compatibility on modern devices, MP4 is typically the better choice. 3G2 is specifically useful for older CDMA phones and size-constrained scenarios.

Works in Any Browser

Our converter runs entirely in your web browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • Even works on mobile devices

No plugins, no downloads, no registration. Just upload, convert, and download.

Pro Tip

When converting for MMS sharing, aim for files under 1MB for best compatibility across all carriers. If your video is longer than 30 seconds, consider trimming it before conversion or reducing quality settings.

Common Mistake

Using 3G2 for modern smartphones when MP4 would provide better quality. 3G2 is specifically optimized for older CDMA phones—if your device is from after 2015, you likely don't need this format.

Best For

Sending video clips to users with older CDMA phones or when MMS file size limits are a concern. Also useful for archiving videos in a compact format.

Not Recommended

Don't convert to 3G2 if you plan to watch on a modern smartphone, tablet, or computer. The quality loss isn't worth it for devices that support higher-quality formats like MP4 or even the original MPEG.

Frequently Asked Questions

3G2 is a multimedia container format developed by 3GPP2 for CDMA-based mobile phones. It stores video encoded with H.264 or MPEG-4 and audio with codecs like EVRC or QCELP. The format is optimized for small file sizes and mobile network transmission.

3GP was created for GSM networks, while 3G2 was designed for CDMA networks. Both are similar formats based on the ISO base media file format, but they use different audio codecs optimized for their respective network types. 3G2 supports CDMA-specific codecs like EVRC and QCELP.

There will be some quality reduction because 3G2 uses lower resolution and bitrate optimized for mobile screens. However, on small phone displays, the difference is minimal. The tradeoff is significantly smaller file size, which is essential for mobile storage and transmission.

In our testing, 3G2 files are typically 60-70% smaller than the original MPEG. A 100MB MPEG video might convert to a 30-40MB 3G2 file, depending on the content and original quality settings.

Most modern Android and iOS devices can play 3G2 files, though the format is designed for older phones. For modern smartphones, MP4 is generally a better choice as it offers higher quality and universal support.

Yes, MPEG and MPG refer to the same video format. MPG is just a shorter file extension commonly used on Windows systems, while MPEG uses the full format name. Both contain video compressed with MPEG-1 or MPEG-2 codecs.

Yes, our converter supports batch processing. Upload multiple MPEG files and convert them all to 3G2 in one session, saving time when processing video collections.

3G2 videos are typically converted to resolutions like 176x144 (QCIF) or 320x240 (QVGA), which are standard mobile video sizes. These lower resolutions help keep file sizes small and ensure smooth playback on mobile devices.

Yes. The conversion happens directly in your browser using client-side processing. Your video files are not uploaded to any external server, keeping your content private and secure.
