About the Code Minifier tool
Code Minifier compresses your HTML, CSS, or JavaScript by removing comments, line breaks, and extra spaces. Smaller files load faster and use less bandwidth, which helps your website's speed and SEO. Paste your code, choose the language, and the Code Minifier shows how many characters you saved. It is a lightweight helper, ideal for quick optimizations before deploying.
