CSS Beautifier: Format CSS, LESS, and SCSS Online
CSS Beautifier uses Prettier, the same formatting engine used by VS Code, to turn messy or minified CSS into readable, consistently formatted code. It supports CSS, LESS, and SCSS syntax, with settings for 2-space, 4-space, or tab indentation and a configurable print width. Paste your input, choose the formatting options, and copy the result; processing stays in your browser with no upload.
CSS Beautifier formats CSS, LESS, and SCSS with Prettier, the same formatting engine used by VS Code. It turns messy or minified stylesheet code into a more readable layout, making the result easier to inspect, review, and share. Paste your code in the browser, choose the formatting options, and copy the output when it is ready.
The formatter supports 2-space, 4-space, or tab indentation, as well as a configurable print width. These settings control how indentation appears and how long formatted lines can be. The tool focuses on formatting the input; it does not describe a conversion from CSS to LESS or SCSS, or the reverse.
CSS is the standard stylesheet language, while LESS and SCSS are CSS-related stylesheet syntaxes with additional authoring conventions. A CSS Beautifier is useful when you want code in one of these supported syntaxes to be more consistent and readable without manually adjusting whitespace. This can make a stylesheet easier to review, compare, or include in a report.
CSS Beautifier runs entirely in your browser. Your input is processed on your device and is not uploaded or sent to a server; after the page has loaded, the tool can also work offline. This makes it a practical option for developers and DevOps engineers who want a quick way to format stylesheet code while keeping it on their own device.
Step 1: Paste your CSS, LESS, or SCSS code into the input. You can use a readable stylesheet or a minified snippet.
Step 2: Choose an indentation style: 2 spaces, 4 spaces, or tabs. Set the print width to control how long formatted lines can be.
Step 3: Review the formatted output. If the input does not parse cleanly, use the reported line to find where it needs attention.
Step 4: Copy the beautified code and use it in your project, review, or documentation.
Use case: Make an unreadable, machine-generated CSS file easier to review before committing it.
Use case: Check a CSS document you did not write against the formatting style your project follows.
Use case: Format CSS, LESS, or SCSS consistently so code diffs show meaningful changes instead of whitespace noise.
Use case: Beautify a stylesheet snippet before adding it to a bug report or code review.
Use case: Check whether a stylesheet parses cleanly and locate the line where formatting encounters a problem.
Use case: Adjust indentation and print width to make stylesheets easier for your team to scan.
Use case: Reformat minified stylesheet code when you need to inspect its rules during debugging.
