Frequently Asked Questions
What does HTML beautification do?
Beautification adds proper indentation, line breaks, and spacing to minified or messy HTML code. It makes the structure clear and readable by consistently indenting nested elements.
What does HTML minification do?
Minification removes unnecessary whitespace, comments, and line breaks from HTML to reduce file size. This helps web pages load faster by transferring less data over the network.
Is my HTML data sent to a server?
No. All processing happens directly in your browser using the js-beautify library. Your HTML code is never uploaded to any server โ privacy guaranteed.
What HTML versions are supported?
The formatter handles HTML5, XHTML, and legacy HTML. It properly handles void elements (like <br>, <img>, <input>) that don't need closing tags, and preserves inline elements without adding unwanted whitespace.
Can I use this to fix broken HTML?
This tool formats (beautifies) valid HTML โ it does not fix missing tags or invalid syntax. For broken HTML, use a validator first, then format the corrected code here.
