Svg icons vs. PNG icons in modern web sites
Opt for SVG for scalable icon requirements and an uncompromised responsive design. SVG boasts lossless scaling and lends support to CSS and JavaScript for interactivity. Use PNG for images which are simpler and do not require scaling. Here's a quick SVG example:

SVGs: Dynamic and interactive
SVGs are masters of interactivity. With big gun JavaScript, SVG icons can morph on the fly, permitting behaviours such as color-shifting in response to user inputs. Costume changes for SVGs are easy with CSS— creating dynamic hover effects or animated transitions. Beware of the potential performance impacts on mobile browsers and older devices; SVGs can be heavier on CPU compared to PNG.
PNGs: For the simpler chores
PNGs come into light for their simple designs and uniform performance across legacy browsers. While they miss out on the interactive journey, PNGs can be leaner for basic icon designs, shrinking the data payload and load time. Techniques such as data URIs allow you to embed PNG icons directly into stylesheets—cutting back on extra HTTP requests and perfect for limited color icons.
Optimizing file size
SVGs come with a catch—they may contain excess metadata that can bloat file size. Compressors like SVGO step in here to optimize your SVGs without fracturing the visuals. For best results, test the compressed SVGs extensively to ensure no broken functionalities. PNGs on the other hand, can gain performance advantage via spritesheets, albeit with third-party tools but offering an efficient way of managing multiple icons.
High definition clarity
SVGs bring their A-game to high-resolution displays—remaining crisp and unblurred on any screen size. PNGs, can become pixelated once you scale them up. The vector-based nature of SVG ensures that your design elements are always pixel-perfect.
Handling icon-heavy sites
Icon-rich websites could turn SVGs into webfonts to improve performance and reduce server requests. Maintain fallback mechanisms, like PNG substitutes for edge cases where SVGs might strain older devices.
What suits your site?
The choice between SVG and PNG hinges on the unique needs of your website. If you're seeking dynamic, responsive, and modern designs, SVG is your buddy. Stick to PNG for simpler graphics or when complete support for older browsers is a must. Also, weigh the quantity of icons and the extent of graphic modification during your decision process.
