Introducing the HTML Formatter — Beautify & Minify

Production HTML usually arrives as one endless line — valid, but impossible to read. The new HTML Formatter re-indents it so the structure is obvious, and can minify clean markup back down for shipping, all in your browser.

What it does

• Beautify: indent each element at a depth that reflects its nesting.
• Minify: strip insignificant whitespace and comments for production.
• Indentation: choose 2 spaces, 4 spaces, or tabs.
• Safe: preserves the verbatim content of pre, script, style, and textarea.
• Private: everything runs client-side; nothing is uploaded.

Why it matters

Indented markup makes mismatched tags, missing closers, and odd nesting jump out, so debugging and code review get faster. The transform is non-destructive for ordinary HTML, so you can beautify to read and minify to ship without ever changing what the page renders.
