About the CSS & JavaScript Minifier
Minification strips comments, whitespace, and line breaks from your CSS and JavaScript without changing how the code works. Smaller files download faster, which improves page speed and Core Web Vitals — a direct ranking factor.
This minifier processes everything in your browser, so your source code never leaves your machine.

Frequently asked questions
Does minifying change how my code behaves?
No. Minification only removes characters that browsers ignore (whitespace, comments). The functionality stays identical.
How much smaller will my files be?
It depends on formatting, but CSS and JS files typically shrink by 20–60%, and even more when combined with gzip or Brotli compression.
Is my code uploaded anywhere?
No. Minification runs entirely in your browser, so your code is never transmitted or stored.
