Scalable Vector Graphics (SVG) is a web-friendly image format that stays sharp at any size, unlike JPEGs or PNGs, which can become pixelated at larger sizes. SVGs use mathematical equations to draw shapes, making them perfect for logos, icons and illustrations that need to look crisp across different screen sizes. An SVG will look equally sharp on both a mobile phone and a large desktop monitor while maintaining fast page speeds.
