Format ugly HTML code into readable structure. This page is designed to help you work with the result with a clear browser-based workflow rather than making you install a separate utility for a small task.
Paste the source text, apply the transformation, inspect the changed text, and copy the result only after checking punctuation, spacing and meaning.
Use it when you need a focused result without installing a separate desktop application. Automated text transformations can change formatting or context. Keep the source text when exact wording matters.
Expected: A result that matches the options you selected and can be checked against the original input. Avoid: Using the output immediately without checking a representative part of it first.
Text transformations are easiest to trust when you can compare the result with a small sample first. Use HTML Beautifier on representative text, confirm that punctuation, whitespace, markup or character encoding behaves the way you expect, and only then process larger blocks. Keep a copy of the source when wording or structure matters, because some transformations are intentionally destructive or difficult to reverse exactly. For structured text or markup, test the result in its destination as well so syntax and escaping still behave as intended.
