Code Formatter

Code Formatter beautifies messy or minified source code into a clean, consistently indented form that is easy to read and review. It supports HTML, CSS, JavaScript, and XML, applying language-appropriate rules for indentation, line breaks, and structure so nested tags, rules, and blocks line up predictably.

You control the output style by choosing an indent size of 2, 4, or 8 spaces, or switching to tabs, and the formatter applies your choice uniformly throughout the file. A minify option does the opposite, stripping unnecessary whitespace and line breaks to shrink code for production. Because formatting changes only spacing and layout, never the underlying logic, your code behaves exactly as before. All processing happens locally in your browser, so proprietary code is never sent to a server.
