Did You Know?
HTML minification can reduce the size of a typical webpage by 5% to 20% depending on the amount of comments and whitespace.
HTML (HyperText Markup Language) is the backbone of the web, used to structure and describe the content of web pages. While developers use indentation and comments to make code maintainable, these extra characters are ignored by browsers during rendering. HTML minification matters because it creates the leanest possible version of your site's structure, ensuring that your production environment is as efficient as possible without changing how the page looks to the end user.
Best Practice

However, if you use white-space: pre in your CSS or rely on spaces between inline-block elements, you should test your layout after minification.
Q: Does this tool minify the CSS and JavaScript inside my HTML? A: This specific tool focuses on the HTML structure and whitespace. For best results, use our dedicated CSS and JS minifiers for internal or external scripts.
Q: Can I edit the code after it has been minified? A: It is very difficult to edit minified code because it lacks formatting. Always keep your original source files and use this tool for the final production version.
