HTML CSS JS Minifier FAQ

What is code minification?

Code minification removes unnecessary characters like whitespace, comments, and line breaks from source code without changing functionality. This reduces file size and improves page load times.

Should I minify my HTML, CSS, and JavaScript?

Yes, for production websites. Minification reduces file size by 20-60%, improving page load speed and bandwidth usage. However, keep the original unminified files for development.

What's the difference between minification and beautification?

Minification compresses code by removing whitespace and comments to reduce file size. Beautification (or prettifying) adds proper indentation and formatting to make code more readable for developers.

Can minified code be reversed?

Minified code can be beautified to add formatting back, but comments and some original spacing cannot be fully recovered. Always keep your original source files.

Does minification affect code functionality?

No, minification only removes unnecessary characters. The code functionality remains exactly the same. However, always test minified code before deploying to production.

Is it safe to minify my code here?

Yes, all minification and beautification happens entirely in your browser. Your code never leaves your device or gets sent to any server.
