Will it fix broken HTML?

It reformats indentation and spacing, but it doesn't validate or repair structurally invalid markup.

Does it minify instead of format?

No — this tool expands and indents HTML for readability. For minification, use a dedicated minifier.

Is embedded CSS or JavaScript also formatted?

Formatting focuses on the HTML structure; content inside and tags may not be reformatted.
