What is SVG?
Scalable Vector Graphics
SVG is an XML-based vector image format that scales to any size without quality loss. It's the universal standard for icons, logos and illustrations on the modern web — but to use one as a regular bitmap (favicon, social card, app asset) you need to rasterize it first.

When to use SVG
Reach for SVG when you need icons, logos and ui illustrations on the web, rasterizing vector art into png for favicons or social cards, exporting design assets at a specific pixel size, generating app icons in multiple resolutions. It excels at these scenarios because scales to any resolution without quality loss and tiny file sizes for icons and simple graphics.
Pros
- +Scales to any resolution without quality loss
- +Tiny file sizes for icons and simple graphics
- +Editable as text, styleable with CSS
When to avoid SVG
Avoid SVG when not a bitmap — must be rasterized to use in non-web contexts, and not suited for photographs. In those cases, look at the alternatives below.
Cons
- −Not a bitmap — must be rasterized to use in non-web contexts
