JavaScript Minifier

工具介绍

Compact JavaScript by stripping comments and collapsing safe whitespace — with strings, template literals, and regex literals preserved exactly. Runs in your browser, no upload.

工具概览

This is a lightweight, conservative JavaScript minifier. It walks your source one token at a time, leaving every string, template literal, and regular expression untouched while removing line and block comments and shrinking runs of whitespace where it is safe to do so. It does not rename identifiers, shorten property accesses, or perform tree-shaking — for that you want a full bundler. What it does well is compressing snippets, examples, inline scripts, and configuration code without changing their behavior.

使用场景

• Inline a small snippet into HTML where every byte matters.
• Quickly minify a code sample for a documentation page or blog post.
• Pre-process configuration scripts before piping them into a CMS field.

输入/输出示例

// say hi
function hi(name) {
  return `Hello, ${name}!`;
}

function hi(name){return `Hello, ${name}!`;}
