Frequently asked questions
Does formatting change my HTML semantics?
Formatting adds whitespace between tags for readability. Minifying removes extra whitespace without changing structure.
Can I minify HTML for production?
Yes. Switch to minify mode to produce a compact single-line snippet.
Are attributes with special characters supported?
Yes. The formatter respects quoted attribute values when indenting tags.
