What is Code Minifier?
A Code Minifier reduces the size of source code by removing unnecessary characters — whitespace, comments, and redundant syntax — without altering its behavior. Smaller code means faster downloads, reduced bandwidth, and better performance.
This tool supports JavaScript & TypeScript (via Terser), CSS (via clean-css), HTML (via html-minifier-terser), and a smart basic minifier for PHP, Python, SQL, JSON, and plaintext — all running 100% in your browser.
How to Use This Code Minifier
- Select your programming language from the dropdown.
- Paste your code into the input textarea, or click "Example" to load sample code.
- Customize the minification options (appear based on the selected language).
- Click "Minify" to compress your code.
- Copy the minified output using the copy button.
Frequently Asked Questions
Which languages are supported?
Advanced: JavaScript, TypeScript (Terser), CSS (clean-css), HTML (html-minifier-terser). Basic: JSON, PHP, Python, SQL, and plaintext — comments and extra whitespace are stripped safely.
Is my code stored on a server?
No. All processing happens entirely in your browser using client-side libraries. Your code never leaves your device.
Will minification break my code?
Advanced minifiers (Terser, clean-css) are designed to preserve functionality. The basic minifier only removes comments and extra whitespace — it cannot change logic. Always test minified code in your target environment.
