Minified or hand-mangled HTML is painful to read. This tool fixes that: paste it and the html beautifier reformats it into a clean, indented tree in your browser, free. As an html formatter it keeps your code on your device and hands back markup you can actually follow.
Cramped markup becomes a readable tree.
Paste cramped markup and the tool adds indentation and line breaks, turning it into beautiful html you can scan. It is an html beautifier and an html formatter in one, and people reach it as a html code beautifier, a html code formatter, or an html beautifier online. The action, sometimes called html beautify online or html prettify, is a single click.
Whatever phrasing you use, from format html code online to free html formatter to the html formatter online variant, and even the common typo html fromatter, the output is the same: a clean tree with a consistent html indent online style.
Legibility, not just formatting.
Once markup is formatted, it reads cleanly, so the tool doubles as an html viewer for tangled code. Call it an html viewer online, an online html viewer, or an html online viewer; the point is legibility. It also works as an html code reader and an html code viewer when you just need to follow the nesting rather than edit anything.
It formats code, it does not run it.
This formats code rather than rendering it, so it is not an html preview or an html preview online, and not an html css js online compiler that executes your page. It is not an html website inspector like a browser's dev tools, and it does not act as an html output online view or an html code output generator. For a live render, paste the formatted markup into a browser.
Tidy is not the same as correct.
Beautifying reformats without judging, so it is not an html validator, an html code checker, or an html parser online that builds a document tree. It will indent invalid markup just as happily as valid markup. To confirm the page is correct, open the tidy output in a browser or a dedicated validator, then minify it for production when you are done.
Stop reading. Start using.
