Indent

Format Any HTML

Paste minified, one-line, or messy HTML to get clean indented output. Each tag on its own line with proper nesting depth. Perfect for reading view-source output, debugging template output, and learning from other sites' markup.

Self-Closing Tags

Void elements (br, img, input, meta, link, hr) don't increase indent. pre and textarea content is preserved byte-for-byte.

FAQ

Does it validate HTML?
No — it only re-indents. Use the W3C validator for syntax errors.

Why Use This HTML Beautifier?

The HTML Beautifier runs entirely in your browser, which means three things matter for you. First, it's instant — there's no server round-trip, no upload, no waiting on someone else's queue. Second, it's private — nothing you enter ever leaves your device, which makes it safe for sensitive numbers, draft copy, or files you don't want sitting on a third party's servers. Third, it's free forever — no signup, no email capture, no "basic vs. pro" upsell. Open the page, get the answer, close the tab.

Common Use Cases

Everyday lookups when you need a fast, reliable answer without installing an app
Cross-checking results from another tool or spreadsheet when accuracy matters
Quick reference during work calls, school assignments, or planning sessions
Sharing the link with a colleague or friend who needs the same answer
Bookmarking for repeat tasks that come up regularly throughout the week

Privacy & How Your Data Is Handled

Every calculation and every transformation in the HTML Beautifier runs locally in your browser using standard JavaScript. We don't upload your input to any server, we don't log it, and we don't pass it to a third-party API. The tool works the same whether you're on a fast home connection or completely offline once the page has loaded. If you want to verify this for yourself, open your browser's network tab and run the tool — you won't see any outbound request carrying your data.

Is my data safe?
