What is SVG compression?
SVG compression is the process of minifying Scalable Vector Graphics (SVG) markup XML data. SVG is an XML-based vector format, which means it describes paths and colors using text rather than a grid of pixels. Illustrator and design editors write a large amount of redundant metadata, editor dimensions, and styling blocks. Compressing SVGs strips these details, minifies whitespace tags, and yields a significantly lighter file size with identical visual representation.
