About JavaScript Minifier

Runs Terser, the minifier behind most build tools, inside your browser. Compression removes dead code and shortens expressions; mangling shortens local variable names.

Syntax errors are reported with a line and column. Module mode allows stricter output for import/export code.

How to use it

  1. 1Type or paste your text, or open a file.
  2. 2Choose any options - the result updates as you type.
  3. 3Copy the result or download it as a file.
