Frequently Asked Questions
Does formatting fix invalid HTML?
It improves readability. Broken tags still need manual fixes; validators catch structural problems better.
Will it change how the page renders?
Whitespace-only formatting usually does not change rendering. Minify carefully around significant whitespace in preformatted content.
Is HTML uploaded?
No. Formatting runs in your browser.
