What Is Stylus to CSS?
Stylus is a CSS preprocessor with optional braces, variables, mixins, and nesting. Like Sass and Less, it compiles to standard CSS for browsers. This tool converts Stylus to CSS in your browser—no build step required. The W3C CSS spec defines the output.
Paste Stylus or upload a .styl file. The tool handles variables, nesting, and the & parent selector. It runs entirely in your browser. For SCSS or Less, use SCSS to CSS or Less to CSS. For formatting the output, use CSS Formatter.
How to Use This Tool
Paste or Upload Stylus
Paste your Stylus code into the left editor or click Upload to load a .styl file. Use Sample to load example Stylus with variables and nesting.
Review the CSS Output
The right panel shows the compiled CSS. For complex Stylus (mixins, functions, imports), the official Stylus compiler may be needed. For validation, use CSS Validator.
Copy or Download
Use Copy or Download to save the CSS. For minifying, use CSS Minifier. For converting CSS to SCSS or Less, use CSS to SCSS or CSS to Less.
Where Stylus Conversion Helps
Stylus is used in projects built with Vite, Webpack, or Gulp. When you need to compile a snippet without a full build, or inspect what Stylus produces, this tool helps. Build pipelines typically use the official Stylus package.
For other preprocessors, use SCSS to CSS or Less to CSS. For combining CSS files, use CSS Combiner. For extracting CSS from HTML, use CSS Extractor.
Frequently Asked Questions
Is my data private?
Yes. Conversion runs entirely in your browser. No data is sent to any server.
Does it support all Stylus features?
This tool supports variables, nesting, and the & parent selector. Mixins, functions, @import, and other advanced features may need the official compiler.
Stylus vs SCSS vs Less?
All are CSS preprocessors. Stylus has minimal syntax (optional braces/semicolons). SCSS is CSS-compatible. Less is similar to SCSS. Use the one that fits your stack.
What about darken(), lighten()?
Built-in Stylus functions like darken() are not evaluated by this basic converter. For full support, use the official Stylus compiler in your build.
Can I convert CSS to Stylus?
This tool converts Stylus to CSS only. For CSS to another preprocessor, use CSS to SCSS or CSS to Less.
