Bitmap images like JPEGs, GIFs, and PNGs all look awful when you scale them up, so if you want to maintain quality at large dimensions you have to increase file size. SVG images however (which stands for Scalable Vector Graphics) look exactly the same, regardless of the dimensions they’re scaled to and they keep the same file size.
Let’s look at SVGs for web design, in sixty seconds!
Understanding SVG for Web Design
SVGs can be used vis CSS as backgrounds, or you can place them in content as regular images. You can create icons and logos which always look perfect at any size, they can be animated and morphed, and you can apply cool filters and effects to them (check out the SVG filter demo by Lucas Bebber below). You can even control their colouring with CSS.
On the inside an SVG file is just readable, editable XML code. And text within SVGs is normal, indexable, search-engine-friendly text.
You can create SVGs with virtually any vector graphic editing program, like Affinity Designer, Boxy SVG, Illustrator, Gravit Designer, or Inkscape. Just create your image, export it as SVG, and it’s ready for use in your websites. That’s SVG for web design, in sixty seconds!
