JavaScript 미니파이어
Terser로 JavaScript를 온라인에서 축소: 변수 맹글링, 데드 코드 제거, 절감률 표시까지 모두 브라우저에서
JavaScript Minifier Tips
- Powered by Terser - the same engine behind webpack, Vite and Rollup production builds.
- Mangling renames local variables to short names; disable it if you need readable stack traces.
- Dead code like unused functions is dropped automatically by the compressor.
- Minified ES modules still need a bundler for import/export resolution - minify bundles, not modules.
전문적인 JavaScript Minifier 처리 기능
JavaScript Minifier 데이터를 효율적이고 전문적으로 다루는 데 필요한 모든 것
Terser Engine
The same battle-tested minifier that powers production builds of webpack and Vite.
Clean Output
Comments stripped, whitespace collapsed, code restructured for minimal size.
Dead Code Removal
Unused variables, unreachable branches and redundant logic disappear automatically.
Mangle Control
Toggle variable mangling with one checkbox - readable when you need it, tiny when you ship it.
Size Report
Bytes before and after, plus the exact percentage saved, on every run.
Private by Design
Your source code stays in the browser tab. Nothing is uploaded, ever.
작동 방식
전문가처럼 JavaScript Minifier을 처리하는 간단한 단계

자주 묻는 질문
Js Minifier 서식 지정에 대한 일반적인 질문에 답변합니다
Yes, completely free with no registration. All minification happens locally in your browser.
Terser - the industry-standard minifier used by webpack, Vite, Rollup and many other bundlers for their production builds.
Mangling renames local variables and functions to 1-2 character names for extra savings. Enable it for production; disable it when you need readable stack traces or debug the output.
It can compress the syntax, but module specifiers are left as-is. Bundle your code first (e.g. with a bundler), then minify the bundle for the best result.
Typical well-commented, readable source shrinks 40-60% with mangling enabled; already-compact code shrinks less. The size report shows the exact savings.
