JavaScript Minifier
Minify JavaScript code by removing whitespace, comments, and optimizing for production.
-
CSS minification mostly means shortening declared values, a color code, a unit, a shorthand property, but JavaScript actually has logic behind it, variables, functions, branches that never execute, which means real JS minification means renaming local variables down to single letters since a descriptive name and a single character run identically, and stripping out code that can never actually be reached. This tool minifies JavaScript by removing whitespace and comments while applying these logic-aware optimizations, built for a language with actual control flow rather than CSS's flatter set of declared values.

Useful for shrinking a production JavaScript bundle beyond what basic whitespace stripping alone achieves, renaming verbose local variable names automatically without touching a function's actual public API, or stripping genuinely unreachable code out of a file before it ships.
