Compare Scalable Vector Graphics and Web Open Font Format 2 formats — understand the key differences and when to use each
Scalable Vector Graphics
SVG (Scalable Vector Graphics) is an XML-based vector image format developed by the W3C. Unlike raster formats (JPG, PNG), SVG describes images using mathematical paths, shapes, and text, allowing them to scale to any size without quality loss — from a tiny icon to a billboard. SVG supports styling via CSS, animation via SMIL or JavaScript, interactivity, accessibility features, and embedded fonts. SVG files are typically much smaller than raster equivalents for logos, icons, and illustrations. Because SVG is text-based, it can be indexed by search engines, edited in any text editor, and manipulated with JavaScript in web applications. SVG supports filters, gradients, patterns, clipping, and masking. It's the standard format for web icons, logos, data visualizations (D3.js, Chart.js), and responsive graphics. All modern browsers natively render SVG.
Web Open Font Format 2
WOFF2 is the second generation of the Web Open Font Format, using Brotli compression for 30% better compression than WOFF1. WOFF2 is the recommended font format for modern websites, providing the smallest file sizes while maintaining full glyph fidelity. It's supported by all modern browsers.
