What does code minification do?
Minification removes unnecessary characters from code — such as whitespace, comments, and newlines — without changing functionality. This reduces file size and improves page load speed.
Is my code safe? Does it get uploaded anywhere?
Completely safe. All minification happens 100% in your browser using JavaScript. No code is ever sent to any server. Your code stays private on your device.
Will minification break my code or change functionality?
No. Our minifier strictly follows industry standards. It only removes whitespace, comments, and redundant characters. The code logic and functionality remains identical after minification.
How much can minification reduce file size?
Typically 20–80% depending on the code. Well-commented and formatted code can see dramatic reductions. This directly improves your Google PageSpeed score and Core Web Vitals.
What is the Full Minifier (All) mode?
The Full Minifier lets you minify HTML, CSS, and JavaScript all at once in a single view — perfect for processing multiple files simultaneously without switching tabs.

Why Minify Your Code?

Code minification is an essential optimization technique for web developers. By removing whitespace, comments, and unnecessary characters from HTML, CSS, and JavaScript files, you can significantly reduce page load times, improve Core Web Vitals scores, and provide a better user experience.

Google's PageSpeed Insights and Lighthouse tools recommend minifying resources as one of the top performance improvements. Faster websites rank higher in search results, have lower bounce rates, and convert better — making code minification a crucial step in any web development workflow.

Our free online code minifier supports all three core web technologies: HTML minifier for markup optimization, CSS minifier for stylesheet compression, and JavaScript minifier for script optimization. Use it for any project — from simple websites to complex web applications.

`, css: `/* Main Stylesheet */ body { margin: 0px; padding: 0px; background-color: #ffffff; } .container { width: calc(100% - 20px); /* This calc function is now protected */ }`, js: `// Utility Functions function initApp(selector) { debugger; var element = document.querySelector(selector); // 'element' will be minified safely if (!element) { console.error("Element not found:", selector); return null; } // Notice the comment inside the regex is preserved now var trickyRegex = /https:\/\//g; return true; }` }; samples['all-html'] = samples.html; samples['all-css'] = samples.css; samples['all-js'] = samples.js;function loadSample(type) { const inputId = type.startsWith('all') ? type + '-input' : type + '-input'; const el = document.getElementById(inputId); if (el && samples[type]) { el.value = samples[type]; const prefix = inputId.replace('-input',''); const cid = prefix + '-in-count'; updateCount(inputId, cid); showToast('📄 Sample code loaded!', 'info'); } }// ── Toast ── function showToast(msg, type = 'info') { const tc = document.getElementById('toastContainer'); const t = document.createElement('div'); t.className = 'toast ' + type; t.textContent = msg; tc.appendChild(t); setTimeout(() => { if (t.parentNode) t.parentNode.removeChild(t); }, 3000); }// ── FAQ ── function toggleFaq(el) { el.parentElement.classList.toggle('open'); }// ── Keyboard shortcut (Ctrl+Enter = minify) ── document.addEventListener('keydown', (e) => { if ((e.ctrlKey || e.metaKey) && e.key === 'Enter') { const active = document.querySelector('.mode-tab.active'); if (active) { const mode = active.dataset.mode; if (mode === 'all') minifyAll(); else minifyCode(mode); } } });
