MPEG (Moving Picture Experts Group) format encompasses MPEG-1 and MPEG-2 video standards from the 1990s. MPEG-1 was used for Video CDs (VCDs) and early digital video, while MPEG-2 became the standard for DVDs and digital television. MPEG files tend to be large because these older codecs are far less efficient than modern H.264.
MPEG files tend to be large compared to optimized MP4. Converting from MPEG to MP4 H.264 typically reduces file size by 40-80% while maintaining excellent visual quality. The resulting MP4 also plays on every device and platform without compatibility issues.
MPEG was developed by ISO/MPEG in 1993. It uses the MPEG Program Stream container and typically contains MPEG-1/MPEG-2 encoded video. Browser support is very limited, and mobile support is limited. For streaming, MPEG offers mpeg-ts for broadcast capabilities.
Keep MPEG if you're doing professional editing and need the original codec quality. Convert to MP4 when: you need to share the video online, upload to social media, send via email, or reduce storage usage. For 99% of sharing and consumption purposes, MP4 is the better format.

When you upload a MPEG file, SquishVideo first analyzes the video stream to understand its codec, resolution, framerate, and bitrate profile. We then transcode the video to H.264 MP4 using optimized encoding parameters. The entire process preserves audio quality (re-encoded to AAC) and maintains the original resolution unless a lower resolution would provide a better quality-to-size ratio.
MPEG files typically come from: DVD rips, TV capture cards, older camcorders, and broadcast recording equipment.
SquishVideo supports 20+ video formats. Choose your input format:
