SCSS Beautifier

The SCSS Beautifier is a free online tool that reformats messy or minified SCSS into clean, properly nested, readable stylesheets. Paste your code into the input panel, pick your indentation, and it re-indents every rule, variable, and nested block in an instant.

It is powered by Prettier, the same opinionated formatter used across professional front-end teams, running entirely in your browser. Your styles never leave your machine.

What is an SCSS beautifier?

An SCSS beautifier takes Sass source that has been collapsed onto one line or indented inconsistently and rebuilds it with a predictable structure.

It gives each declaration its own line, indents nested selectors under their parents, and normalizes the spacing around braces, colons, and commas.

The result is code that maps cleanly to the nesting you actually wrote, so you can read, review, and edit it with far less friction.

How to beautify SCSS

1. Paste or type your minified or messy SCSS into the input panel on the left.
2. Choose your indentation: 2 spaces, 4 spaces, or tabs.
3. Set a print width of 80, 100, or 120 characters, or choose no-wrap to keep lines intact.
4. Click Beautify to pretty-print the styles into the output panel.
5. Use Copy or Download to grab the formatted .scss file.

Why nesting and indentation readability matters

SCSS earns its power from nesting, and nesting only helps if the indentation makes the hierarchy obvious at a glance.

When a build tool, a copy-paste, or a minifier flattens that structure, a stylesheet becomes a wall of braces where you can no longer tell which selector belongs to which parent.

Consistent two-, four-, or tab-based indentation restores that visual tree, so scoping bugs and stray declarations jump out instead of hiding.

What Prettier normalizes in your SCSS

Prettier does more than add line breaks. It rewrites your styles to a single consistent standard.

It normalizes indentation, collapses or expands whitespace around braces and colons, and enforces one declaration per line.

It also standardizes quote style and trims redundant spacing, so two files formatted by the tool look identical in structure even if they started out wildly different.

SCSS-specific syntax it handles

The beautifier understands the full SCSS feature set, not just plain CSS rules.

• Variables such as $primary and $spacing are aligned with clean spacing after the colon.
• Nesting is reindented so child selectors sit neatly under their parents.
• Parent selectors using the & reference, like &:hover or &.is-active, keep their place in the tree.
• Mixins and includes with @mixin and @include are formatted with consistent argument spacing.
• Control flow such as @if, @else, and @each loops is indented as readable blocks.
• Interpolation like #{$name} inside selectors and values is preserved exactly.

It keeps both // single-line comments and /* */ block comments intact, so your notes survive formatting untouched.

Does it also work with LESS?

Yes. Because the tool uses Prettier's PostCSS-based engine, it also tidies LESS-style nesting and variables.

If you paste LESS with nested rules and & parent references, the beautifier reindents it the same way it handles SCSS, giving you clean, consistent output either way.

Beautify vs. minify for Sass

Beautifying and minifying are opposite ends of the same workflow.

You beautify while you are reading, reviewing, or editing source, because the whitespace makes the nesting obvious and keeps diffs clean.

You minify the compiled CSS right before you ship, when smaller payloads matter more than readability. If you want to compress the final stylesheet, the CSS Minifier strips it down for production once your Sass is compiled.

Local, private, and browser-based

All formatting happens locally in your browser through Prettier. Nothing is uploaded, logged, or stored on any server.

That makes the tool safe for proprietary design systems and private component libraries, since your source never leaves the tab.

The one requirement is valid SCSS. If the input has an unclosed brace or broken syntax, Prettier cannot parse it and the tool shows a clear error pointing you to the problem instead of producing mangled output.

When to use the SCSS Beautifier

Reach for it whenever you inherit a stylesheet that was flattened, exported on one line, or formatted by three different people.

It is ideal for auditing a theme's Sass partials, cleaning up a snippet pasted from a build artifact, or normalizing a file before you commit it so the diff stays meaningful.

If your workflow spans more of the front end, the JS & CSS Beautifier tidies plain stylesheets and scripts, the SVG to CSS tool turns vector icons into embeddable background styles, and the Remove Comments utility strips annotations once you are ready to hand off a lean file.

Frequently Asked Questions

Is my SCSS uploaded to a server?

No. All formatting happens locally in your browser using client-side JavaScript. Your SCSS is never sent to, stored on, or seen by any server, which makes the tool safe for proprietary design systems and private stylesheets.

What engine formats the code?

The tool uses Prettier, the widely adopted opinionated code formatter, self-hosted and run directly in your browser. Prettier reindents your styles and normalizes spacing, quotes, and one declaration per line to a single consistent standard.

Does it also handle Sass and LESS?

Yes. It formats SCSS and Sass, and because it uses Prettier's PostCSS-based engine it also tidies LESS-style nesting and variables. Nested rules and parent-selector references are reindented cleanly whichever syntax you paste.

Does formatting change the compiled CSS?

No. Beautifying only adds or normalizes insignificant whitespace, indentation, and quote style in your source. It does not alter selectors, values, variables, or logic, so the CSS your Sass compiles to stays exactly the same.

Can I choose tabs instead of spaces?

Yes. You can format with 2-space, 4-space, or tab indentation to match your project's coding style, and you can set a print width of 80, 100, or 120 characters or disable wrapping entirely.

Does it keep my comments?

Yes. Both single-line comments written with two slashes and block comments wrapped in slash-star are preserved through formatting, so your notes and section headers survive untouched in the output.
