About JavaScript Minifier
JavaScript minification removes all unnecessary characters from source code — whitespace, comments, newlines, and long variable names — without changing functionality. Minified code loads faster, reducing page load time and bandwidth usage. This is a standard step in web development build processes.
How to Use
Paste your JavaScript code into the input area. Click 'Minify' to compress it. The minified output appears on the right along with the original vs. minified file size comparison. Click 'Copy' to copy the minified code, or 'Beautify' to format it back to readable code.
Common Use Cases
- Minifying JavaScript for production builds to reduce bundle size
- Compressing inline scripts in HTML files
- Reducing bandwidth usage for CDN-served scripts
- Preparing bookmarklets with minimal footprint
- Analyzing code size before and after optimization
