Reduce your JavaScript and TypeScript file sizes and boost performance with our free online minifier. Remove unnecessary whitespace, comments, and formatting to optimize your code for production environments.
Best Practice
Always keep your original source files; minified code is intentionally difficult to read.
Did You Know?
Minification can reduce script file sizes by up to 40%, significantly improving mobile performance.
JavaScript is the fundamental language of the web, used to create interactive and dynamic content. TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. Both are essential for modern web development, but their verbose nature during development can lead to large file sizes. Minification bridges the gap between readable source code and efficient production assets.
Tip
Use source maps in your build process to debug production errors using your original source code.
While online tools are great for quick tasks, consider these methods for professional workflows:
Q: Does minification change how my code functions? A: No, minification only removes non-functional elements like whitespace and comments; the logic remains identical.
Q: Can I minify TypeScript directly? A: Yes, our tool handles TypeScript syntax, but remember that for production browsers, you typically compile TS to JS first.
Q: Should I minify my code manually every time? A: For large projects, we recommend using build tools like Vite or Webpack, but this online tool is perfect for quick optimizations and testing.
Best Practice
Combine minification with Gzip or Brotli compression for maximum file size reduction.
