What Is CSS to SCSS?
SCSS adds variables, nesting, and mixins to CSS. Converting plain CSS to SCSS restructures it with nesting and prepares it for SCSS features. This tool analyzes your CSS and outputs SCSS-style structure. The W3C CSS specifications define the source; Sass defines the output.
Conversion runs entirely in your browser. Nothing is sent to a server. The output is valid SCSS. For the reverse (SCSS to CSS), use SCSS to CSS. For Less, use CSS to Less.
How to Use This Tool
Paste or Upload CSS
Copy your CSS and paste it into the left editor. You can also click Upload to load a .css file. The Sample button loads example data. Invalid CSS will show an error.
Review the SCSS Output
The right panel shows converted SCSS. Selectors may be nested where structure allows. You can add variables and mixins manually after conversion.
Copy or Download
Use Copy or Download. Compile the SCSS with SCSS to CSS to verify. For formatting CSS first, use the CSS Formatter.
When CSS to SCSS Helps
When migrating a project from plain CSS to SCSS, or when you have CSS from a design export and want to integrate it into an SCSS-based codebase (e.g. Bootstrap 4+, Foundation), this conversion provides a starting point. Build tools like webpack and Vite compile SCSS. The output gives you nested structure you can refine with variables and mixins.
Design tools like Figma often export plain CSS. Converting to SCSS here lets you add it to a component-based structure. For Less instead, use CSS to Less. For vendor prefixes, use the CSS Prefixer.
Frequently Asked Questions
Does it add variables or mixins?
The converter focuses on structure (nesting). It doesn't automatically extract repeated values into variables. Add variables and mixins manually based on your needs.
Is my data private?
Yes. Conversion runs entirely in your browser. No data is sent to any server.
How does nesting work?
The tool infers nesting from selector relationships. Complex selectors may remain flat. Review and adjust as needed.
CSS to SCSS vs CSS to Less?
Both produce preprocessor syntax. SCSS is more widely used (Bootstrap 4+, many frameworks). Less is used by Bootstrap 3, Ant Design. Choose based on your stack.
Can I compile the output?
Yes. Paste the SCSS into SCSS to CSS to compile and verify. The output should match your original CSS structure.
