About HTML formatter
The HTML Formatter takes minified or messy HTML and outputs properly indented, readable code. Paste HTML from a single-line string, a compressed build output, or poorly formatted markup — the formatter adds consistent indentation and line breaks so the structure is clear. Useful for debugging rendered HTML, reviewing third-party embeds, and making hand-edited HTML readable before committing. Copy the formatted output to paste into your editor or save to a file.
