What is 3G2?

3GPP2 (3G2) is a multimedia container format developed for CDMA mobile networks, supporting video and audio streaming.

What is WEBM?

WebM is an open media file format designed for the web, using VP8/VP9 video codec and Vorbis/Opus audio.

When Should You Use 3G2 vs WEBM?

Use 3G2 When...

Reach for 3G2 when your priority is legacy mobile video, mms messages — its efficient compression makes sharing fast and storage minimal.

Use WEBM When...

Reach for WEBM when your priority is web video, html5 video embedding — its efficient compression makes sharing fast and storage minimal.

3G2 vs WEBM: Key Differences

  • •The core technical difference: 3G2 relies on lossy compression whereas WEBM uses lossy compression.
  • •Neither format changes compression philosophy — both are lossy compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
  • •Transparency: N/A
  • •File sizes: 3G2 files typically range Small, optimized for mobile and WEBM files Slightly smaller than MP4 at equivalent quality.
  • •Use case fit: 3G2 targets legacy mobile video, mms messages and WEBM targets web video, html5 video embedding — your choice depends on which workflow stage you are serving.

Advantages of 3G2

  • ✓3G2 compresses data using lossy methods, keeping file sizes manageable for Legacy mobile video, MMS messages.
  • ✓Industry-wide support means 3G2 files open anywhere — from legacy systems to the latest devices.
  • ✓Small file sizes make 3G2 ideal for email, web uploads, and cloud storage.
  • ✓From professional software to open-source alternatives, 3G2 works out of the box.

Advantages of WEBM

  • ✓The lossy nature of WEBM means file sizes stay reasonable while handling Web video, HTML5 video embedding efficiently.
  • ✓From mobile devices to enterprise servers, WEBM is recognized and supported everywhere.
  • ✓Storage and bandwidth costs drop significantly when using WEBM thanks to its efficient compression.
  • ✓WEBM is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Troubleshooting 3G2 to WEBM Conversion

  • !WEBM won't play on target device → check codec compatibility (H.264 has broadest support)
  • !Audio out of sync after 3G2 to WEBM conversion → try re-muxing with a different container format
  • !WEBM quality is too low → increase the bitrate; for 1080p video, 8-15 Mbps is recommended
  • !File size increased converting 3G2 to WEBM → lossless or higher-bitrate outputs naturally produce larger files
