§ Specs
How it Works
JavaScript Minification
We utilize Terser, the
industry-standard JS compressor, running completely locally via WebAssembly/WebWorker in
your browser. It safely removes whitespace, mangles variables, and drops dead code.
CSS Minification
CSS is minified via a fast regex-based parser that strips
multi-line comments, tabs, newlines, and unnecessary spaces around colons, brackets, and
commas.
Security First
Because all processing happens directly in your browser, your
proprietary or sensitive code is never uploaded to any server. Check your network tab to
verify!

Frequently Asked Questions
Minification removes whitespace, newlines, comments, and shortens variable names without changing the functionality of the code. This reduces the file size for faster browser downloading.
Generally, no. We use Terser, an industry-standard minifier. However, if your code has missing semicolons or relies on specific function names (like in some reflection patterns), aggressive minification might cause issues. Always test your minified code.
Smaller files mean faster download times for your users, better Core Web Vitals scores, improved SEO, and reduced bandwidth costs for your servers.
