Format, clean & indent your CSS code in one click. Paste your minified, messy, or unformatted CSS
and get perfectly structured, readable code back instantly — no login, no cost.
A CSS beautifier online tool automatically reformats CSS (Cascading Style Sheets) code to make it clean, readable, and consistently structured. It corrects indentation, normalizes spacing between properties and values, organizes selector blocks, and removes unnecessary blank lines — transforming raw or minified CSS into professionally formatted code in seconds.
Whether your CSS was minified for production, copied from a browser's developer tools, generated by a CSS framework, or written quickly without consistent formatting — ToolsVenue's CSS formatter restores it to clean, readable code instantly.
Faster debugging
Properly indented CSS makes it trivial to find which selector is applying a specific rule — saving minutes of guesswork in developer tools.
Consistent team standards
When multiple developers work on the same stylesheet, consistent formatting eliminates merge conflicts caused by style differences and makes code reviews faster.
Easier maintenance
A well-structured stylesheet is far easier to update six months later — whether it's yours or someone else's.
Framework output cleanup
CSS generated by tools like Tailwind, SASS compilers, or design systems often arrives unformatted. One pass through our CSS code beautifier fixes this instantly.
Client delivery quality
When handing off a project, clean, readable CSS demonstrates professionalism and reduces support questions.
| Feature | What It Does for You |
|---|---|
| Indent Size Control | Choose 2 spaces, 3 spaces, 4 spaces, 8 spaces, or a tab character. Matches your team's style guide or personal preference exactly. |
| Max Preserve Newlines | Control how many blank lines are kept between rule blocks: remove all extras, keep 1, 2, 5, or unlimited. Perfect for maintaining your preferred vertical rhythm. |
| Newline Between Rules | Toggle whether each CSS rule (property: value;) gets its own line — essential for the standard expanded formatting most developers prefer. |
| Selector Separator Newline | Automatically add a newline between grouped selectors (e.g., h1, h2, h3 → each on its own line) for maximum readability. |
| Preserve Newlines | Optionally preserve intentional blank lines you've placed in your CSS to maintain logical groupings and section breaks. |
| One-Click Copy | Copy your beautifully formatted CSS to the clipboard instantly — ready to paste directly into your editor, CMS, or version control commit. |
| Keyboard Shortcut | Press Ctrl+Enter to trigger beautification without reaching for the mouse — built for developer workflow speed. |
| Instant In-Browser Processing | All formatting happens locally. Your CSS code is never sent to any server — complete privacy for proprietary stylesheets. |

The full workflow — paste, configure, beautify, copy — takes under 15 seconds. Most users skip step 3 entirely, as the defaults work perfectly for standard CSS projects.
Format stylesheets before committing to a Git repository, after pulling minified CSS from a third-party library, or after receiving design-system output. Ensures consistent formatting across every file in your project.
CSS from Figma, Webflow, Adobe XD, or other design-to-code tools is often structurally inconsistent. Run it through our CSS formatter online to clean it up before integrating it into a live project.
Paste any CSS snippet — from a tutorial, Stack Overflow answer, or example file — and immediately see how professionally formatted CSS should look. One of the fastest ways to internalize good CSS structure.
CSS added via theme customizers, page builders, or plugin settings often loses its formatting. Clean it up with our CSS beautifier before adding it to your stylesheet or custom CSS box.

| Question | Answer |
|---|---|
| Is this CSS beautifier free? | Yes. ToolsVenue's CSS Beautifier is 100% free with no usage limits and no account required. |
| Does the CSS formatter work with CSS3? | Yes. The formatter handles all CSS3 properties, custom properties (CSS variables), media queries, pseudo-classes, pseudo-elements, and modern CSS features like grid and flexbox. |
| Can I format SCSS or SASS with this tool? | The tool is optimized for standard CSS. SCSS may partially work for basic formatting, but for full SCSS/SASS support, a dedicated SASS formatter is recommended. |
| Will formatting my CSS break anything? | No. CSS formatting only affects whitespace and indentation — browsers ignore these entirely when rendering. Your page will look and behave identically after formatting. |
| Is my CSS code uploaded to a server? | No. All formatting is performed locally in your browser. Your CSS code never leaves your device. |
| What is the best indent size for CSS? | 2 spaces is the most widely adopted standard in modern web development (used by Google, Airbnb, and most major style guides). 4 spaces is also common. Tab character is preferred when your team uses tab-based indentation in their editor. |
| Can I beautify minified CSS from a library? | Yes. Paste any minified CSS — from Bootstrap, Tailwind output, or any other source — and the beautifier will expand and format it correctly. |
| What is the keyboard shortcut to beautify? | Press Ctrl+Enter (or Cmd+Enter on Mac) to trigger beautification without clicking the button. |
Paste your CSS in the input panel, set your preferences, and click Beautify. Clean, professionally formatted CSS code appears instantly — ready to copy directly into your project.
