Code Minifier & Beautifier Overview

Reduce the size of your JavaScript, CSS, or HTML by stripping whitespace, comments, and unnecessary characters. The minified output loads faster and uses less bandwidth. Paste your code, pick the language, and get a compact version ready for production.

How to Use

  1. 1Paste your source code into the editor
  2. 2Select the language (JavaScript, CSS, or HTML)
  3. 3Click Minify to generate the compressed output
  4. 4Copy or download the result

Key Features

  • JavaScript, CSS, and HTML minification
  • Whitespace and comment removal
  • Size comparison showing bytes saved
  • Copy and download minified output
  • Preserves code functionality

Common Use Cases

  • Optimizing page load times

    Minify CSS and JavaScript assets before deployment to reduce file sizes and improve page performance.

  • Reducing bandwidth usage

    Smaller files mean less data transferred, which matters for mobile users and metered connections.

  • Preparing inline scripts

    Minify code before embedding it inline in HTML to keep page size down without a separate build step.

Under the Hood

Minification removes everything the browser does not need to interpret the code — comments, extra spaces, line breaks, and sometimes shortens variable names. The result is functionally identical to the original but significantly smaller. For CSS, it also merges shorthand properties where possible. For HTML, it collapses whitespace between tags.

Frequently Asked Questions

Does minification change how the code works?

No. Minification only removes characters that have no effect on execution — whitespace, comments, and formatting. The behavior stays identical.

Can I reverse minification?

You can re-format (pretty-print) minified code to make it readable again, but original comments and variable names are lost permanently.

How much smaller will my code be?

Typical savings range from 20% to 60% depending on how much whitespace and commentary the original contains.
