About CSS Formatter & Minifier

This tool gives you two essential CSS operations in one place. Paste your CSS and either format it for readability or minify it for production use. After processing, you can see size statistics showing the original and output file sizes, so you know exactly how much space you have saved or how the formatting has affected the file.

How to Use

Paste or type your CSS into the input area. Choose whether you want to format or minify the code. The processed output appears instantly, ready to copy. Size statistics are displayed so you can compare the before and after file sizes at a glance.

Features

  • Format CSS with consistent indentation, newlines, and spacing for improved readability.
  • Minify CSS by removing all whitespace, line breaks, and comments to reduce file size.
  • View size statistics comparing original and processed output.
  • Runs entirely in the browser with no server-side processing, keeping your code private.
  • Copy the result to your clipboard with a single click.

Frequently Asked Questions

What does CSS formatting do?
Formatting takes compressed or poorly indented CSS and restructures it with consistent indentation, line breaks, and spacing. Each rule gets its own line, properties are indented within selectors, and braces are placed on predictable lines. This makes the code much easier to read and maintain.
What does CSS minification do?
Minification removes all unnecessary characters from your CSS, including whitespace, line breaks, and comments. The result is a smaller file that is functionally identical to the original, which helps reduce page load times when used in production.
How are CSS comments handled?
When formatting, comments are preserved in the output so you keep your documentation and annotations. When minifying, all comments are stripped out to reduce file size as much as possible.
Is my CSS data kept private?
Yes. All formatting and minification happens entirely in your browser using client-side JavaScript. Your CSS is never sent to a server, so your code stays completely private.
