Code Formatter

Format and beautify HTML, CSS, and JavaScript with consistent indentation and spacing. It turns minified or messy code into a readable, well-structured layout.

Why formatting matters for code

Code that is minified or carelessly indented is hard to read, review, and debug. Formatting applies consistent indentation, line breaks, and spacing so the structure - which block is inside which - becomes visible at a glance. It does not change what the code does; it changes how easily a human can follow it.

This is especially useful when you inherit someone else's compressed code, or paste a snippet from a source that flattened it, and need to understand or edit it.

Where it helps

Reach for it whenever code is hard to read.

  • Un-minifying production code you need to inspect.
  • Cleaning up a messy snippet before committing it.
  • Standardizing indentation across pasted fragments.

FAQs

Does formatting change how my code works?

No. It only changes whitespace and layout - indentation, line breaks, spacing. The logic and behavior are identical; it is purely for readability.

Can it un-minify compressed code?

Yes. It re-adds indentation and line breaks to minified code, making it readable again, though original comments and variable names that were stripped during minification cannot be recovered.

Which languages does it format?

HTML, CSS, and JavaScript. Each has its own formatting conventions, which the tool applies appropriately.

Is my code uploaded?

No. Formatting runs in your browser, so your code stays on your device.

Will it fix errors in my code?

No. It formats layout, not correctness. Syntax errors remain; in fact, clean formatting often makes an error easier to spot.

Can I choose the indentation style?

Formatters typically let you pick spaces or tabs and the indent size, so the output matches your project's conventions.

Does it minify as well as beautify?

This tool focuses on beautifying. For minification, use the dedicated CSS or JavaScript minifiers, which strip whitespace to shrink the file.

Why does my formatted code look different from my editor's?

Different formatters use slightly different default rules. Adjust the options to match your editor, or pick one consistent style for the project.

Can it handle a mix of HTML, CSS, and JS in one file?

It formats embedded CSS and JavaScript within HTML reasonably well, though keeping languages in separate files generally yields the cleanest result.
