PurgeCSS is a tool that removes unused CSS selectors by analyzing content files and matching them against CSS selectors. It ships as a CLI, a programmatic API, and plugins for PostCSS, Webpack, Gulp, Grunt, Gatsby, and Rollup.

Use cases

• remove unused css from my project
• shrink bootstrap css bundle
• purge unused tailwind or framework styles
• optimize css file size for production build
• strip unused selectors from css framework
• integrate css purging into webpack or postcss pipeline

When to choose

• you use a large CSS framework but only a subset of its styles
• you want smaller CSS bundles in a Node.js build pipeline
• you need a PostCSS, Webpack, or Rollup plugin for CSS purging

When to avoid

• your CSS is dynamically generated at runtime with unpredictable class names
• you rely heavily on runtime-computed class names without safelisting
• your project has no build step to run the purge
