Free Compression & Minifier Tools
Minify CSS, JavaScript and HTML, and compress text — smaller files, faster pages
Every kilobyte you ship to a browser costs loading time, and most shipped code carries dead weight: comments, whitespace, long names and repetition. The tools in this category strip that weight. The three minifiers make CSS, JavaScript and HTML production-ready, and the Text Compressor squeezes any text using real compression algorithms.
Minification happens instantly and locally — paste code in, copy compact code out. Because nothing is uploaded, it's safe to minify proprietary source and unpublished work. Each tool reports exactly how many bytes and what percentage you saved.
Minification matters more than most site owners realize: Google's Core Web Vitals reward fast-loading pages, and every unminified stylesheet or script delays first paint. The tools here won't replace a full build pipeline like webpack or Vite for large applications, but for landing pages, WordPress custom CSS boxes, email templates and quick fixes, pasting into a browser tool is dramatically faster than setting one up — and gives you the same production-grade result.
