CSS Minifier

Compress and optimize CSS Code for faster load times

Reduce CSS file size with our free CSS Minifier tool. Instantly remove whitespace, comments, and unnecessary characters to speed up your site.

Every millisecond counts when it comes to page speed — and your CSS files are no exception. Bloated stylesheets with excess whitespace, comments, and formatting can slow down your website and affect user experience.

The CSS Minifier helps you compress and clean your stylesheet code in seconds. Whether you're optimizing a single file or multiple components, this tool reduces file size without altering how your styles render in the browser.

What Does the CSS Minifier Do?

The CSS Minifier removes all characters from CSS code that are not necessary for execution. This includes:

  • Extra spaces and line breaks
  • Indentation and tabs
  • Comments
  • Unused formatting

The result is a minimized version of your stylesheet that functions the same — but loads faster and takes up less space.

Why Use a CSS Minifier?

Unminified CSS can slow down your website, especially when used in larger frameworks or custom themes. Minification reduces file sizes, leading to faster page load speeds and improved performance metrics.

Use the CSS Minifier to:

  • Optimize your CSS before going live
  • Improve Core Web Vitals scores (especially Largest Contentful Paint)
  • Reduce bandwidth usage on high-traffic websites
  • Eliminate unnecessary formatting from exported or third-party code

Features of the CSS Minifier Tool

  • Instant Compression: Paste your CSS and see the minified version immediately
  • Preserve Functionality: Your styles remain intact and render exactly as intended
  • Handles Full Stylesheets: Works with large or modular CSS files
  • Clean Interface: No distractions, no setup — just fast results
  • Copy with One Click: Quickly export your compressed CSS
  • Browser-Based & Free: No downloads or registration required

How to Use the CSS Minifier

  1. Paste your CSS code into the input area
  2. Click “Minify CSS” (or see real-time output)
  3. Copy the minified version and use it in your website, app, or project

It’s perfect for compressing both custom and framework-based stylesheets.

Example Before and After

Original CSS:

css
/* This is a comment */ .container { margin: 0 auto; padding: 20px; color: #333; }

Minified CSS:

css

.container{margin:0 auto;padding:20px;color:#333}

The style remains exactly the same — but the file size is smaller and more efficient.
