JavaScript Minifier

Giới thiệu công cụ

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

Tổng quan công cụ

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.

Trường hợp sử dụng

• 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.

Ví dụ đầu vào/đầu ra
