Code Formatter
Beautify HTML, CSS and JavaScript — re-indent and add line breaks to make messy or minified code readable.
About Code Formatter
The Code Formatter beautifies HTML, CSS and JavaScript: it re-indents nested structures, restores line breaks and spaces things out consistently, turning minified or messy code back into something you can actually read and review.
Paste code directly or upload an .html, .css or .js file, pick the language, and format with one click. The output pane reports the resulting line count and size, and the beautified code can be copied to the clipboard or downloaded as a file.
It is the natural companion to the minifier — use it to unminify a production bundle you need to debug, tidy generated markup, or normalize indentation before a code review. File uploads are processed on the server and cleaned up automatically.
How to use Code Formatter
- Select the language: HTML, CSS or JavaScript.
- Paste the messy or minified code, or upload the file instead.
- Click Format.
- Copy the beautified result or download it as a file.
