Converting GIFs to Video Cuts File Size by 80%. Here Is How.

A 5-second GIF of a UI interaction can easily weigh 8 MB. The same content as an MP4 video is often under 500 KB. That is a 94% reduction in file size with better visual quality. If you are serving GIFs on a website and care about page load performance, converting them to video is one of the highest-impact optimizations you can make. Why the size difference is so dramatic GIF was designed in 1987 for transmitting simple graphics over slow connections. Its LZW compression works on a per-frame basis with a 256-color limit. Each frame is essentially a compressed static image. Modern video codecs like H.264 (used in MP4) and VP9 (used in WebM) use inter-frame compression. They analyze what changes between frames and only encode the differences. For a screen recording where 90% of pixels stay the same between frames, this is enormously more efficient. The codec also uses advanced techniques like motion estimation, variable bitrate, and perceptual optimization that GIF cannot do. The convers
