SCSS / SASS to CSS

Use the dart-sass compiler for accurate output. CSS→SCSS is lossy—see on-page notice.

When to use this tool

  • Pre-compiling SCSS snippets to CSS for a blog post or docs page.
  • Converting a legacy indented SASS file to modern SCSS.
  • Validating SCSS in isolation before wiring it into your build pipeline.

How it works

  1. Paste the source stylesheet.
  2. Select the conversion direction.
  3. Copy the output.
  4. For CSS → SCSS, remember the conversion is lossy: review and tighten manually.

Privacy: This tool runs entirely in your browser. Your input is not sent to our servers.

CSS → SCSS/SASS is inherently lossy (nesting, variables, mixins). This tool compiles SCSS or indented SASS to CSS only.

Frequently asked questions

Is Dart Sass or LibSass used?

Dart Sass — the actively maintained reference implementation. LibSass is deprecated upstream.

Why is my SCSS module failing to compile?

`@use` and `@forward` require resolvable file paths, which this in-browser tool cannot provide. Inline the code or paste the fully resolved stylesheet.

Does it handle CSS custom properties?

Yes. Custom properties pass through unchanged in both directions.
