What is SVG, and why does it matter?
The core idea behind the SVG format, its advantages, and how it differs from raster formats like PNG/JPG.
SVG (Scalable Vector Graphics) is an XML format that describes an image with mathematical paths instead of pixels.
Advantages
Unlimited scalability, small file size (for simple graphics), styling with CSS/JS, and crisp print output.
When it's not a good fit
For content with millions of color transitions, like photos, an SVG's file size balloons — PNG/WebP is a better fit there.
For logos, icons, illustrations and typography work, SVG is almost always the right choice.
