This tool patches one problem at a time
The Performance module in Insight does the same in every audit: Core Web Vitals in every audit — with priorities, history and before/after comparison.
/ About the tool
Why minification actually helps
Minification removes whitespace and comments — the code still works, usually much smaller.
Bundlers (Vite, Webpack, Rollup) do this automatically. This tool is for one-off jobs — a snippet, a static CDN file, or a quick before/after check.
Everything runs in the browser. Your code never leaves the device.

Single-line // and multi-line /* */ — for developers, not end users.
AAA→a
Mangling (JS only)
Shorter variable names. Full pipelines do this in the bundler.
Brotli
Server compression
After minify, the server should still apply Brotli or gzip.

Frequently asked questions
Not in this free tool. Source maps usually come from your build pipeline.
Compile to JS first (Babel/SWC), then minify.
Not here. Use the JS obfuscator for drop-console.
