⚡ CSS Minifier
Compress CSS by removing whitespace, comments, and unnecessary spaces. Reduce file size, improve load times. 100% client‑side.
📖 How to Use CSS Minifier (Step by Step)
- Step 1: Paste your original (unminified) CSS code into the left text area.
- Step 2: Choose your minification options: remove comments, collapse whitespace (aggressive or preserve line breaks), and remove the last semicolon inside blocks.
- Step 3: Click "Minify CSS" – the compressed code appears instantly on the right.
- Step 4: Copy the minified CSS, download it as a `.css` file, or clear everything and try a sample.
- Step 5: Use the "Load Sample" button to see a practical example.
💡 Why Minify CSS?
- ✔️ Reduce file size, which speeds up website loading.
- ✔️ Save bandwidth and improve Core Web Vitals.
- ✔️ Remove comments and whitespace that are only useful for development.
💡 Pro Tip: Use "aggressive" whitespace removal for production. The minified CSS remains valid and can be further gzipped for even better compression.
🔒 100% client‑side • Your CSS never uploaded • Aggressive minification • Zero tracking
