What is an MPG file?
The MPG file extension is functionally identical to the MPEG format, restricted historically to a three-letter filename in MS-DOS and early Windows environments (8.3 filename convention). It typically contains video and audio interleaved in an MPEG-1 or MPEG-2 Program Stream (PS) container. MPG files are standard for VCD (Video CD) and DVD-Video content, utilizing inter-frame compression to reduce file size while maintaining VHS-comparable or broadcast-quality resolution depending on the bitrate and standard version utilized.
How to open an MPG file
Due to its legacy status as a standard distribution format, MPG files open natively on almost all desktop and mobile platforms without external codecs. Windows Media Player, Apple QuickTime, and GNOME Videos handles MPG-1 and MPEG-2 streams automatically. If playback issues occur due to corrupted headers or proprietary data streams, VLC Media Player is the industry-standard fallback utility.

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.
