SVG (Scalable Vector Graphic)
An image made from mathematical paths in XML: scalable and ideal for logos and icons.
An SVG (Scalable Vector Graphic) is an image made from mathematical paths written in XML, rather than a fixed grid of pixels like a JPEG or PNG. Because it's described by shapes instead of pixels, an SVG scales from a tiny favicon to a full-screen banner without ever going blurry, which makes it ideal for logos and icons on sharp modern displays. It's also tiny: a logo that weighs 100 KB as a PNG might be 2 KB as an SVG, which helps load times. WordPress blocks SVG uploads by default because, being code, they can carry malicious scripts, so the right way to enable them is to add support through a plugin that sanitizes the files rather than editing core or turning off the safety check.
