Frequently asked questions
Will formatting change how my page looks?
Prettier is careful with whitespace-sensitive inline elements, so rendering should not change.
Is the HTML Formatter free and private?
Yes. The HTML Formatter is free, needs no account, and runs entirely in your browser. What you type is never sent to a server or stored.
