Reduce your JS file size by up to 70%. AST-level minification runs entirely in your browser — no server upload, no data leaves your machine.
Your code never leaves the browser. All parsing, transformation, and minification happen locally using a built-in AST engine — zero server roundtrips, zero data risk.
Goes beyond regex hacks. We parse your code into an abstract syntax tree, apply real transformations — dead code elimination, variable mangling, string collapsing — then regenerate optimal output.
Pick exactly which optimizations to apply. Strip console.log and debugger in production, mangle local variables for maximum compression, or keep your code readable during development.
Copy to clipboard or download as .min.js with one click. Preset examples let you test transforms instantly — jQuery plugins, React components, or utility functions.
