This minifier strips comments and unnecessary whitespace. For production builds with variable-name mangling and tree-shaking, use a parser-based tool like esbuild or Terser.

JavaScript Minifier ์†Œ๊ฐœ

Free online JavaScript minifier. Strip comments, whitespace, and redundant semicolons from JS to reduce file size - typically 20-50% smaller. Handy for one-off pastes when you don't want to spin up a full build pipeline. Runs entirely in your browser. 712 Tools์˜ JavaScript Minifier์€ ์ตœ์‹  JavaScript API๋ฅผ ์‚ฌ์šฉํ•ด ์—ฌ๋Ÿฌ๋ถ„์˜ browser์—์„œ ์™„์ „ํžˆ ๋™์ž‘ํ•ฉ๋‹ˆ๋‹ค - server๊ฐ€ ์—ฌ๋Ÿฌ๋ถ„์˜ ๋ฐ์ดํ„ฐ๋ฅผ ๋ณผ ์ผ์ด ์ ˆ๋Œ€ ์—†์Šต๋‹ˆ๋‹ค. ์ฆ‰, ์ฆ‰๊ฐ์ ์ธ ๊ฒฐ๊ณผ, ์™„์ „ํ•œ ํ”„๋ผ์ด๋ฒ„์‹œ, ๊ทธ๋ฆฌ๊ณ  ์—…๋กœ๋“œ ์ œํ•œ์ด ์—†์Šต๋‹ˆ๋‹ค.

How much smaller does the JS get?

Typically 20-50%. Comment-heavy or well-formatted files shrink more; already-minified code shrinks less.

Does it mangle variable names?

No. Only whitespace and comments are removed - variable names are preserved. For name mangling use a real bundler like esbuild or Terser.

Will it break my code?

It preserves the code's tokens. That said, minification via regex has edge cases with regex literals and template strings - for production code, use a proper parser-based tool.

Is my code uploaded?

No. Minification runs entirely in your browser.
