Frequently Asked Questions
What does the HTML formatter do?
It parses your HTML and reformats it with consistent indentation and line breaks, making minified or messy markup easy to read.
Will it change my HTML content?
The formatter only changes whitespace — text content, attributes, and structure remain intact. Inline elements may be collapsed onto one line.
Is my data sent to a server?
No. All parsing and formatting uses the browser's built-in DOMParser. Your data never leaves your machine.
