SVG Accessibility — Making Icons and Graphics Screen Reader Friendly
Scalable Vector Graphics (SVGs) are a web developer’s go-to for crisp, resolution‑independent graphics. They scale beautifully on any screen, but without the right accessibility handling, SVGs can easily become invisible to users relying on assistive technologies. Ensuring your SVG icons and illustrations are both performant and accessible transforms them from purely decorative visuals into valuable, inclusive UI assets. SVGs often communicate meaning—status icons, charts, and buttons rely on visual indicators. For users with low vision or who use screen readers, missing or ambiguous descriptions can turn SVG visuals into barriers. Accessible SVGs make these visuals perceivable and understandable, aligning with WCAG 2.2 Success Criteria 1.1.1 (Non‑Text Content) and 4.1.2 (Name, Role, Value).SVG Accessibility — Making Icons and Graphics Screen Reader Friendly
Introduction
Why SVG Accessibility Matters
Before adding any accessibility markup, decide whether the SVG is purely decorative or conveys meaning: The combination of Both elements must have unique Use roles and ARIA attributes to clearly define the SVG’s purpose: SVGs become focusable by default in certain browsers, which can clutter keyboard navigation. To prevent unnecessary focus: If your application uses SVG icons within a component library, ensure all components pass accessibility parameters by default: Check how your SVG behaves with assistive technologies: Accessible SVGs bridge the gap between beauty and usability. By providing meaningful titles, roles, and ARIA associations, your icons and graphics become universally perceivable while retaining their flexibility and design scalability. Every line of vector code can help make your interface clearer, inclusive, and WCAG‑compliant. Next Steps: Audit your icon library, classify each SVG as decorative or meaningful, and enrich them with semantic markup. Test your visuals across browsers, keyboard interfaces, and screen readers to confirm consistent accessibility support.Decorative vs Informative SVGs
aria-hidden="true" or role="presentation".<!-- Decorative :: hidden from screen readers -->
<svg aria-hidden="true" viewBox="0 0 24 24">
<path d="..." />
</svg>
<!-- Informative :: exposed to assistive tech -->
<svg role="img" aria-labelledby="title desc" viewBox="0 0 24 24">
<title id="title">Warning</title>
<desc id="desc">Yellow triangle with a black exclamation mark representing a warning message</desc>
<path d="..." />
</svg>
Providing Accessible Titles and Descriptions
<title> and <desc> elements gives screen readers context about what a graphic represents. These should be human-readable and concise:
id values referenced by aria-labelledby or aria-describedby.
Adding ARIA Roles and Labels
role="img" — Identifies the SVG as an image equivalent.aria-label — Provides a concise alternative if no <title> is used.aria-labelledby and aria-describedby — Link visible title and description elements.<svg role="img" aria-label="Success icon">
<path d=" M10 15l5-5-1.4-1.4L10 12.2l-2.6-2.6L6 10l4 5z"/>
</svg>
Focusable vs Non‑Focusable SVGs
focusable="false" for decorative icons.tabindex="-1" if they shouldn't be part of the tab order.<svg aria-hidden="true" focusable="false">
<path d="..." />
</svg>
SVGs in Component Libraries
title or ariaLabel to populate <title> or aria-label dynamically.function Icon({ name, label }) {
return (
<svg role="img" aria-label={label} focusable="false">
<use href={`#${name}`} />
</svg>
);
}

Common Issues in SVG Accessibility
role="presentation" used for meaningful icons hides them from assistive tech.
