CSS and JavaScript formatter

这些新工具的说明和输入字段目前使用英语。

Beautify or minify source text without executing it.

How it works and limits

Prettier formats JavaScript/CSS; Terser minifies JavaScript without compression or identifier mangling, and CSSO minifies CSS without restructuring. Up to 100,000 characters. No source execution, preview, remote imports or source maps. Keep the original and test exported code; these tools are not sanitizers. JSON and HTML remain in their existing tools.

Worked example

language: JavaScript
action: Beautify
source: const add=(a,b)=>{return a+b};

Inputs start empty. Load example fills them only when you choose it. Reset clears inputs and results.

This tool runs locally. When enabled, Google manages regional privacy choices. Google code can access this page and its inputs.
