Ready to beautify
Paste CSS and click Beautify — or press Ctrl+EnterDrop in minified, copied-from-DevTools, or otherwise messy CSS. Any valid CSS is accepted including media queries, keyframes, and variables.
Select 2-space, 4-space, or tab indentation. Optionally sort properties alphabetically or strip comments for a clean output.
Copy the formatted CSS to clipboard with one click, or download it as a .css file ready to drop into your project.
CSS Beautifier is a free browser-based formatter that turns minified or poorly indented CSS into clean, readable code. It handles selectors, rules, media queries, keyframes, CSS custom properties, and nested structures with configurable indentation and optional property sorting.
The beautifier handles all standard CSS including selectors, pseudo-classes, pseudo-elements, media queries, keyframe animations, CSS custom properties (variables), @import and @charset rules, and multi-level nesting. It preserves the logical structure of the original code while adding consistent formatting.
When enabled, the properties within each rule block are sorted alphabetically. This produces consistent, predictable order across your codebase, which reduces merge conflicts in version control and makes code reviews easier since reviewers always know where to find a property.
No. Beautifying only changes whitespace and formatting — it never reorders rules, changes values, or alters the cascade. The only exception is the Sort properties option, which reorders properties within a block. Since CSS declarations in a single block are generally order-independent (with the exception of shorthand-then-longhand conflicts), this is safe for most code.
No. All formatting is done entirely in your browser using JavaScript. Your CSS code is never transmitted to any server. This makes the tool safe to use with private or proprietary stylesheets.
Comments are valuable during development but add bytes in production. Stripping them before deployment reduces file size without requiring a full minification pass. It is also useful when you want a clean, readable file without section annotations that may be out of date.
Beautifying expands CSS with indentation, line breaks, and spacing to make it human-readable. Minifying does the opposite — it removes all whitespace and comments to produce the smallest possible file for production delivery. Use beautify for editing and debugging; use minify for the version you deploy to your server or CDN.
CSS code accumulates in untidy states quickly. Build tools minify stylesheets for production, browser DevTools display computed styles without consistent indentation, and copy-pasting from documentation or Stack Overflow brings in all manner of formatting inconsistencies. A CSS beautifier normalises all of this into clean, consistent, readable code in seconds.
A CSS beautifier parses the structure of CSS — selectors, property blocks, at-rules, and nested contexts — and reformats the text with consistent indentation, one property per line, and proper spacing around braces and colons. The output is functionally identical to the input but laid out in a way that makes it easy to read, edit, and review. It is essentially the inverse operation of minification.
Different codebases have different conventions. Two-space indentation is the most common choice in modern JavaScript-adjacent projects and is the default for many popular formatters like Prettier. Four-space indentation is common in older projects and matches the default in many text editors. Tab indentation uses actual tab characters, which allows each developer to configure their editor to display the width they prefer without changing the source file. This tool supports all three with a simple dropdown.
Alphabetical property sorting is a practice that trades natural grouping for absolute predictability. In an unsorted block, you have to scan the entire rule to find a specific property. In an alphabetically sorted block, you know exactly where every property will be. Tools like Stylelint can enforce this automatically, and this beautifier can pre-sort your properties before you integrate them into a project that uses such linting rules.
CSS comments serve two common purposes: section headers that divide large stylesheets into logical regions, and temporary disabled code. When handing off a stylesheet for production deployment, stripping comments reduces file size without the full overhead of minification. When performing a code review of a third-party library, removing comments can make the actual declarations easier to focus on. The strip-comments option handles both use cases.
One of the most practical uses for a CSS beautifier is cleaning up CSS copied from browser DevTools. When you inspect an element and copy its applied styles, the output is typically a flat list of declarations without selector context, often with browser-injected properties and unusual spacing. Pasting this into a beautifier and reformatting it gives you a usable starting point for adding those styles to your own stylesheet.
The toolbar above the output shows a live count of rules and properties in the formatted CSS. This is useful for quickly assessing the scope of a stylesheet — how many rules it contains, how many declarations are applied — without reading through the entire file. When reviewing third-party CSS before including it in a project, these numbers give you a fast sense of scale.
