🧠 How GIF Works

GIF uses lossless LZW compression but is limited to a 256-color palette per frame. Its main feature is animation support: multiple frames with delays in one file. Transparency is 1-bit only (a pixel is either visible or not). Here is how it works:

🖼 RGB original image 🎨 Palette select 256 best colors key limitation 🔢 Indexing pixel → index in color table 📦 LZW lossless compression (dictionary method) 🎬 Frames delay + dispose = animation 💾 .gif final file
