What is a 3G2 file?
The 3G2 file format is a multimedia container defined by the 3rd Generation Partnership Project 2 (3GPP2) for use on CDMA2000-based mobile networks. It is structurally similar to the MP4 format but is optimized to minimize storage and bandwidth usage on legacy mobile devices. The format stores video streams typically encoded with MPEG-4 Part 2 or H.263, and audio streams using EVRC, EVRC-B, QCELP, or SMV codecs. 3G2 files are compliant with the ISO base media file format (ISO/IEC 14496-12) but possess extensions specific to the 3GPP2 specifications.
How to open a 3G2 file
While 3G2 was native to early CDMA mobile phones, modern desktop operating systems often lack native support for its specific audio codecs like EVRC. Apple QuickTime Player and Microsoft Windows Media Player may open these files if the appropriate DirectShow filters are installed. For universal compatibility across Windows, macOS, and Linux, the VLC media player is recommended as it utilizes the FFmpeg library to decode 3GPP2 streams without external codec packs.

What is a WEBP file?
WebP is a raster graphics file format developed by Google specifically for web optimization, utilizing the Resource Interchange File Format (RIFF) container. It employs predictive coding based on the VP8 video codec for lossy compression and the LZ77 algorithm with entropy coding for lossless compression. WebP supports transparency (alpha channel) in both lossy and lossless modes, as well as animation, often achieving file sizes 26-34% smaller than comparable JPEG or PNG files while maintaining high structural similarity (SSIM) index scores.
How to open a WEBP file
WebP is natively supported by all modern web browsers, including Google Chrome, Mozilla Firefox, Microsoft Edge, and Apple Safari. For offline viewing, Windows 10 and 11 support WebP via the Photos app (often requiring the Webp Image Extensions package), while macOS users can view them in Preview (macOS Big Sur and later). Legacy systems or incompatible editors require conversion tools or third-party viewers like IrfanView to render the image data.
