What is the HTML Beautifier?
Copied-from-browser or template-engine HTML is often one long line or inconsistently indented. This beautifier re-indents elements by nesting depth, breaks block elements onto their own lines, and deliberately keeps inline elements (a, span, strong) flowing — so the result reads naturally and diffs cleanly.
Frequently Asked Questions (FAQ)
Q: Will beautifying change how the page renders?
No. Whitespace between block elements is insignificant in HTML rendering; the output is semantically identical.
