SVG - Scalable Vector Graphic

The Scalable Vector Graphic (SVG) is a vector graphic format for displaying scalable 2D objects on the World Wide Web. Developed by the World Wide Web Consortium and based on XML, this format is highly data-efficient. It is used on web pages when graphics need to be displayed in different sizes with sharp clarity, as is the case with logos, for example. This is especially advantageous for responsive websites, as they can adapt their size to the output interface without the need for multiple versions.

Initially, during the 2000s, not all browsers could display these graphics. However, this issue is essentially no longer a problem, as most widely used browsers can now render SVG. Additionally, Google recommends using this format, making it potentially relevant for search engine optimization.
