HTML Beautifier
Format HTML code for better readability

โ FAQ
Q. Can I expand minified HTML?
A. Yes, this converts minified HTML to readable format.
Q. Does it reorder attributes?
A. Currently original attribute order is preserved.
Q. Does beautifying change how the page looks?
A. No. The beautifier only modifies whitespace and indentation. The HTML structure and behavior remain identical. Rendered output in the browser will look the same.
Q. Which HTML versions are supported?
A. HTML5 is the primary target, but XHTML and older HTML versions are also handled correctly. Non-standard tags will still receive proper indentation based on their nesting level.
Q. Can I use tabs instead of spaces for indentation?
A. Currently the tool supports space-based indentation. Choose between 2-space or 4-space indentation to match your workflow.
