Frequently Asked Questions
How does the HTML formatter work? +
The formatter parses your HTML and rebuilds it with proper indentation and line breaks. It recognizes opening tags, closing tags, self-closing tags, comments, and text content, then applies consistent indentation based on your chosen indent size.
Is my HTML data sent to a server? +
No. All formatting happens entirely in your browser using JavaScript. Your HTML never leaves your device — nothing is uploaded or stored anywhere.
Can I format HTML with embedded CSS and JavaScript? +
Yes. The formatter preserves the content inside style and script tags as-is while properly indenting the surrounding HTML structure. The embedded code blocks are kept intact.
What indent options are available? +
You can choose between 2 spaces, 4 spaces, or tabs for indentation. Select your preference from the dropdown before formatting, or change it and re-format at any time.
Does the formatter fix broken HTML? +
The formatter focuses on indentation and readability — it does not fix missing closing tags or correct invalid HTML structure. For best results, ensure your HTML is valid before formatting.
