How to use the HTML formatter

Drop in your HTML, or upload an .html file. The formatted result appears right away.
Pick Format or Minify
Choose Format to indent the markup cleanly, or Minify to strip it down to a single compact line. Set the indent size when formatting.
Copy or Download
Copy the result or download it as an .html file, ready to drop back into your project.
Readable HTML, Without the Hand Editing
HTML has a way of turning into one long unreadable line. Markup copied from a page source, output from a builder, or pasted from a minified file all arrive squashed together, with no indentation to show what sits inside what. Reading it, or finding a bug in it, becomes a chore.
This formatter fixes that. It walks the markup tag by tag and rebuilds it with clean, consistent indentation, so the nesting is obvious and the structure is easy to scan. Void tags like img and br are handled correctly, and the contents of script, style, pre, and textarea are left exactly as they are so nothing breaks.
When you need the opposite, switch to minify and the same markup collapses to a single compact line for production. Pick your indent size, paste your HTML, and copy the result. It all runs in the browser, so even private templates stay on your machine.

Frequently Asked Questions
Common questions about formatting HTML.
What does formatting HTML do?
Formatting, or beautifying, rewrites your markup with consistent indentation and line breaks so the nesting of tags is clear. It does not change what the HTML does, only how it looks in the editor.
Does it change my JavaScript or CSS?
No. The contents of script, style, pre, and textarea are kept as they are. Indentation is added around them, but the code inside is preserved so it still runs the same.
What is the difference between format and minify?
Format spreads the markup out with indentation to make it readable. Minify does the reverse, stripping line breaks and extra spaces to make the file as small as possible for production.
Can I choose the indent size?
Yes. Switch between two spaces, four spaces, or tabs to match the style your project uses.
Will it fix broken HTML?
It tidies the formatting based on the tags you give it, but it does not repair invalid markup or add missing closing tags. Start with valid HTML for the best result.
Is this HTML formatter free?
Yes, it is completely free with no signup and no limits. Everything runs in your browser, so your markup stays on your device.
