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.
Minify CSS and JavaScript assets before deployment to reduce file sizes and improve page performance.
Smaller files mean less data transferred, which matters for mobile users and metered connections.
Minify code before embedding it inline in HTML to keep page size down without a separate build step.
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.
No. Minification only removes characters that have no effect on execution — whitespace, comments, and formatting. The behavior stays identical.
You can re-format (pretty-print) minified code to make it readable again, but original comments and variable names are lost permanently.
Typical savings range from 20% to 60% depending on how much whitespace and commentary the original contains.
