Definition
An HTML Formatter (often called a Beautifier or Pretty Printer) is a tool that takes messy, unformatted, or minified HTML code and restructures it with consistent indentation and line breaks, making it easily readable by humans.
Use Cases
While browsers can read HTML no matter how messy it is, humans cannot. Formatting your code is essential for maintenance.
The Mechanics
The formatter analyzes the DOM structure of your code and applies indentation rules based on parent-child relationships.
2 SpacesThe most common standard for modern web development (React, Vue, HTML5).
4 SpacesOften preferred in older codebases or backend-heavy templates.
TabsUses the tab character (\t), allowing the viewer's editor to define the visual width.
Capabilities
Paste your messy HTML and instantly see it beautified without any page reloads.
Your HTML is processed entirely in your browser. We never send your code to our servers.
Automatically recognizes inline tags (like `<span>` or `<a>`) to prevent awkward line breaks.
Instantly copy the beautified HTML to your clipboard ready for your editor.
Step-by-Step
Paste your messy, minified, or unformatted HTML into the left input panel.
Select whether you want 2 spaces, 4 spaces, or Tab characters for your indents.
The tool will instantly generate a clean, readable version in the right panel.
Click the 'Copy' button and paste the clean code back into your text editor.
FAQ
Usually, no. Browsers collapse multiple spaces and line breaks into a single space. However, if you have elements with the CSS property `white-space: pre` or are using `<pre>` tags, adding indentation inside those tags will affect the visual output.
If you've finished editing your formatted HTML and are ready to deploy it to a live website, use our HTML Minifier to compress it first.
