About JavaScript Minifier

Compress JavaScript using Terser. Removes comments, shortens variable names, and eliminates dead code. Output is valid JavaScript semantically identical to the input.

JavaScript Minifier is part of FizzKit — a collection of focused, browser-based tools. Because everything runs locally, it works offline once loaded and never exposes your data to a remote server.
