About RTSoftwares
A free, no-signup JavaScript minifier and beautifier - paste JS, upload a file, or load from a URL, then minify it to save bytes (using Terser, a real production-grade minifier with proper parsing and variable renaming) or beautify it into clean, readable code. Runs entirely in your browser; nothing you paste or upload is ever sent to a server.
JS Minifier is built and maintained by RTSoftwares. We build small, free, no-signup web tools that run entirely in your browser.
