Why Format Code?

Consistent formatting makes code easier to read, review, and maintain. But different projects use different styles — tabs vs. spaces, semicolons vs. no semicolons, single quotes vs. double quotes. This tool lets you format (or minify) code in multiple languages with syntax-highlighted preview, all in the browser.

Supported Languages

JavaScript, TypeScript, JSON, HTML, CSS, and more. Select a language, paste your code, and hit Format. The side-by-side CodeMirror preview shows the result with proper syntax highlighting so you can verify it looks right before copying.

Minification

Need to shrink your code for production? The minify option strips whitespace and shortens where possible. It's not a full bundler — for that you'd use Webpack or esbuild — but it's handy for quick one-off minification of a config file or snippet.
