What is the HTML Formatter Tool?

HTML Formatter is a free web utility that takes minified, single-line, or poorly indented HTML markup and reformats it with consistent line breaks and nested indentation, so it's easier to read and debug. Everything runs locally in your browser (html-formatter) — your markup is never sent to a server.

Why Format Your HTML?

HTML returned by APIs, build tools, or copied from a "View Source" panel is often compressed into a single dense line. Reading or editing markup in that state is error-prone — closing tags get lost, nesting becomes invisible, and small bugs are hard to spot. Reformatting restores a clear, indented tree structure that mirrors how the elements are nested.

Key Features

  • Automatic Indentation: Detects opening and closing tags and indents nested elements accordingly.
  • Fully Client-Side: Formatting happens entirely in your browser. No HTML you paste in is ever uploaded anywhere.
  • No Setup or Sign-up: Nothing to install or register for. It is instantly ready to use.
  • Responsive Layout: Works cleanly on desktop, tablet, and mobile screens.

How to Use This Tool?

  1. Paste your raw or minified HTML into the input field.
  2. Click Format HTML.
  3. The indented result appears instantly in the output box below.
  4. Select and copy the formatted markup to use in your project.

Why Choose Our Client-Side Tool?

Many online formatters send your markup to a remote server before returning the result, which is a concern if your HTML contains proprietary templates or unreleased code. This tool reformats everything directly inside your browser tab, so nothing ever leaves your device.
