🗜️HTML / CSS / JS Minifier
Minify HTML, CSS, or JavaScript to shrink file size — using proper minifiers, with a bytes-saved readout and copy/download.
Free HTML, CSS & JavaScript Minifier
Need to shrink your code? Our free HTML minifier — plus CSS and JavaScript — strips out comments and unnecessary whitespace to make your files smaller and faster to load. Paste your code, pick the language, and get clean minified output instantly, along with a clear readout of exactly how many bytes and what percentage you've saved.
It uses proper minifiers under the hood, so your code is compressed correctly without breaking strings, comments inside strings, or important licence banners. Switch between HTML, CSS, and JavaScript, copy the result, or download it as a file ready to drop into production. If your code has a syntax error, you'll get a clear message instead of broken output. And because everything runs in your browser, your source — even proprietary code — never leaves your device.
Simply paste your code to minify it instantly. No sign-up, no downloads, no limits — just smaller files, privately.
