Compare TrueType Font and Scalable Vector Graphics formats — understand the key differences and when to use each
TrueType Font
TTF (TrueType Font) is a scalable font format developed by Apple and Microsoft in the late 1980s as a competitor to Adobe's PostScript fonts. TTF uses quadratic Bézier curves to define glyph outlines, providing high-quality rendering at any size. TrueType fonts include hinting instructions that optimize rendering on screen at small sizes. TTF is supported by all major operating systems and applications. While OpenType (OTF) has largely succeeded TrueType for professional typography, TTF remains widely used and universally compatible.
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.
