The Code Minifier Tri-Pack shrinks HTML, CSS and JavaScript by stripping comments, collapsing whitespace and removing redundant syntax — safely, and entirely in your browser. Switch between the three tabs, paste your code, and instantly see the minified output alongside before-and-after byte counts and the percentage saved, ready to copy or download. Every kilobyte you remove is a kilobyte visitors no longer download and parse, which shortens load times, trims bandwidth bills, and nudges your Core Web Vitals and PageSpeed scores in the right direction.
This free tool by Hosting Cambodia is deliberately conservative so it never breaks your code: the HTML pass preserves everything inside pre, textarea, script and style tags plus IE conditional comments; the CSS pass keeps strings and calc() expressions intact; and the JavaScript pass is a safe whitespace-and-comment minifier — not a compiler — that respects strings, template literals and regex literals without renaming a single variable. Keep your readable originals for editing and serve the minified copies, exactly as professional build pipelines do.
Frequently asked questions
Can minification break my JavaScript?
This tool is built not to. It only removes comments, blank lines and trailing whitespace while understanding strings, template literals and regular expressions, and it never renames variables or restructures logic. The trade-off is a slightly smaller saving than an aggressive compiler like Terser, in exchange for total safety.
How much does minification actually improve page speed?
Typical savings are 10 to 30 percent for hand-written code, and more for comment-heavy files. The gain compounds with gzip or brotli compression on your server, and smaller JavaScript also parses and executes faster, which helps Interaction to Next Paint on mobile devices.
Should I edit the minified files afterwards?
No — always keep your original, readable source files and re-minify after every change. Minified code is for serving to browsers, not for maintenance; treating it as a build output ensures you never lose the readable version.
