+If possible, the utilisation of svg image format (or `` html tag) is recommended over other image format.
+
+Because SVGs are generally smaller than other image format, theyβre less taxing on your server despite needing to render on load.
+
+When to use SVG :
+
+- Your image is used for decorative website graphics, logos, icons, graphs and diagrams, and other simple images.
+- You image require animation.
+- You image need to be responsive and scale without lack of quality.
+
+Some advantages of using SVG:
+
+- SVGs are scalable and will render pixel-perfect at any resolution whereas JPEGs, PNGs and GIFs will not.
+- SVGs are vector images and therefore are usually much smaller in file-size than bitmap-based images.
+- SVGs can be embedded into the HTML which means they can be cached, edited directly using CSS and indexed for greater accessibility.
+- SVGs can be animated directly or by using CSS or JavaScript making it easy for web designers to add interactivity to a site.
