왜 이것이 최고의 온라인 HTML 포매터인가

포맷 & 미화 HTML

Paste minified or poorly indented HTML and get back cleanly structured code with consistent indentation. Supports 2-space, 4-space, and tab indentation. Void elements like <br>, <img>, and <input> are handled correctly.

구문 강조

Color-coded tag names, attributes, values, comments, and doctype declarations make formatted HTML easy to review. The output panel renders the highlighted code without executing it.

HTML 압축

Strip all formatting whitespace and HTML comments to produce compact, production-ready HTML. Reduces file size and speeds up page load time without changing how the page renders.

개인정보 우선

All processing runs entirely in your browser — no HTML is ever sent to a server. Safe for templates containing sensitive data, internal admin pages, or proprietary front-end code.

자주 묻는 질문

What is an HTML formatter?

An HTML formatter (also called a beautifier or pretty printer) takes raw or minified HTML and reformats it with consistent indentation and line breaks, making the code easier to read and debug. It does not change how the HTML renders in a browser.

Does formatting HTML change how it looks in the browser?

No. HTML formatters only add or remove whitespace between tags. Browsers collapse multiple whitespace characters in most contexts, so formatting changes are invisible to end users. The only exception is content inside pre or textarea elements, where whitespace is significant.

What is HTML minification?

HTML minification removes unnecessary whitespace and comments to reduce file size. Minified HTML loads faster because smaller files transfer more quickly over the network. It is commonly applied to production HTML by build tools like webpack or Vite.

Why is my HTML indentation inconsistent?

Inconsistent HTML indentation is usually caused by mixing spaces and tabs, copying from different editors, or manual editing errors. Pasting your HTML into this formatter and applying a consistent indent style fixes all indentation at once.
