Safe to use

Your HTML is only re-indented as text. It is never rendered or run, so scripts in your input can’t do anything.

Questions about HTML Formatter

More answers in the TextVix FAQ.

Will formatting change how my page looks?

Inline elements such as <b> and <a> stay within their lines, and <pre> and <textarea> content is untouched, so rendering is preserved in normal cases.

Is my text uploaded anywhere?

No. This tool runs entirely in your browser. Your text and files are never sent to a server or stored.
