Why do you need this tool?
Slow Page Load Times
Uncompressed CSS and JavaScript files block rendering and drastically increase your First Contentful Paint (FCP) time.
Bandwidth Costs
Serving bloated text files with thousands of spaces and comments costs you money on AWS or CDN bandwidth.
Deployment Friction
Setting up Webpack or Gulp just to minify a single legacy script file is overkill and wastes developer time.

Frequently Asked Questions
Is minifying JavaScript safe in the browser?
Our tool uses a conservative regex approach for JS to remove comments and blank lines safely. However, for complex modern JS (ES6+), we always recommend using a dedicated AST parser like Terser in your build pipeline.
What exactly does the CSS minifier do?
It strips all block comments `/* ... */`, removes unnecessary spaces around brackets and colons, collapses all line breaks, and drops trailing semicolons to squeeze every possible byte out of the file.
Is my code sent to a server?
No. All minification algorithms run natively in your browser using JavaScript. Your code never leaves your device.
