Frequently Asked Questions
Does formatting change HTML behavior?
No. Formatting only changes whitespace (indentation, line breaks), which HTML ignores. The browser renders formatted and minified HTML identically. Formatting is purely for human readability and has zero impact on functionality.
Can it handle malformed HTML?
Best effort. Severely malformed may not format.
Is my data processed locally?
Yes, all processing happens in your browser. No data is sent to any server.
