How do I convert LESS to CSS?

Paste or upload your .less file into the converter. Choose optional settings like minification or line breaks. Click the conversion button. The tool parses all LESS logic—variables, mixins, nesting—and outputs a plain CSS file. Download the result and replace your stylesheet link.

Why should I convert LESS to CSS?

CSS is the only styling language natively supported by browsers. LESS adds variables, mixins, and nesting, but it must be compiled before use. Converting LESS to CSS ensures cross-browser compatibility, eliminates the need for a JavaScript compiler on the client side, and can reduce file size by stripping preprocessor-only syntax.

What happens to LESS variables, mixins, and nested selectors in conversion?

Variables are resolved to their computed values, so the final CSS contains only static values. Mixins are expanded inline at each call site, duplicating their declarations. Nested selectors are flattened into standard descendant syntax, e.g., `.nav .item` instead of `.nav { .item { } }`. Arithmetic operations are evaluated and replaced with the exact result. LESS-specific comments (`//`) are removed, while standard CSS comments (`/* */`) are preserved.
