This plugin adds a Gutenberg block that lets you pick a Dashicon and render it on the frontend as an inline SVG. The icons are lightweight, scalable, and fully customizable, making them ideal for modern WordPress block-based sites.
The plugin does not rely on the traditional icon rendering approach (CSS-based icon fonts with pseudo-elements and large icons.css files). Instead, it uses a far more optimized yet fully compatible method. There is no separate CSS icon font file, and not a single extra asset is loaded on the frontend. Only the pure SVG icon markup is embedded and rendered by the browser. There are no image files and no CSS files involved, while icons remain perfectly sharp at any size.
Why is this plugin beneficial? 
– Easily use Dashicons on the frontend 
– Choose from 334 icons 
– Core Web Vitals friendly 
– No icon font or CSS file loading 
– No images or image files 
– No overengineered or unnecessary features 
– No accessibility-hindering CSS pseudo-elements 
– Icons scale to any size and stay sharp 
– SVG icons appear as clean inline code in the content 
– Secure and validated
Icons the way Gutenberg expects 
The Dashicons set is finally available as a native block element. No HTML hacks, no font dependency — just clean inline SVG markup directly from the editor.
Faster loading, more stable layout 
Instead of downloading and rendering icon fonts, icons appear instantly in the HTML. No FOIT, no CSS pseudo-elements, no CLS risk — better Core Web Vitals and predictable rendering.
Safe SVG usage 
No SVG uploads, no sanitizer, no risky pipeline. The plugin exclusively uses the official SVG sources of WordPress Dashicons — deterministic, verified markup.
JS-free, cache-friendly 
No icon library JavaScript, no sprite loader, no runtime processing. SVG is static HTML — ideal for SSR, static caching, and block themes.
Editor experience for users 
The Dashicons picker block uses a fast, familiar UI. Simple and consistent to use. Content creators choose icons — not edit code.
In your own language 
The plugin can be easily and quickly translated on the official translate.wordpress.org platform, making it even easier to use in your own language.
