Note: Format mode uses js-beautify to pretty-print your HTML with configurable indentation. Minify mode strips comments and collapses whitespace. All processing runs entirely in your browser — no data is sent to any server.

What is HTML Formatter?

HTML Formatter turns compressed or inconsistent markup into readable, properly indented HTML. It is useful for debugging page structure, reviewing templates, and preparing snippets for documentation or code review without sending code to a server.

How to Use HTML Formatter / Minifier

  1. Paste your HTML into the input panel.
  2. Choose whether you want to format or minify the markup.
  3. Adjust indentation options if needed.
  4. Copy the cleaned output for editing, review, or deployment.

Frequently Asked Questions
Does HTML Formatter validate my HTML?

The formatter focuses on indentation and readability. It will process malformed HTML as best it can, but it is not a strict validator. Use a dedicated validator if you need spec-compliance checking.

Will formatting change the rendered output of my page?

No. Adding whitespace between block elements does not change visual rendering. Be cautious with inline elements like <span> inside text where whitespace can matter, but the formatter preserves inline content.

Can I format a full HTML document with <!DOCTYPE> and <head>?

Yes. The formatter handles complete documents including doctype declarations, head sections, scripts, and styles without stripping any content.

Is there a file size limit?

There is no server-side limit because everything runs in your browser. Very large files (hundreds of KB) may take a moment to process depending on your device.
