How to use JavaScript Minifier & Beautifier?
JavaScript files can often become large and slow down your website. Our tool helps you optimize your code for speed or clean it for readability.
- Input: Paste your raw or unformatted JavaScript code into the main editor.
- Minify: Use "Minify JS" to strip out comments and all unnecessary whitespace. This is standard practice before deploying code to a live website to improve load times.
- Beautify: Use "Beautify JS" if you have a single line of compressed code and want to see the logical structure with proper indentation and line breaks.
- Check Stats: View the "Compression" metric to see the effectiveness of the minification process.

Frequently Asked Questions
Will minification change my logic?
No. Minification only removes non-functional parts of the code like comments and spaces. All variables and logic flow remain exactly the same.
What is the difference between Minification and Obfuscation?
Minification aims to reduce file size. Obfuscation aims to make the code unreadable to humans to protect intellectual property. Our tool primarily focuses on size and readability.
Is it safe to beautify third-party scripts?
Yes! Beautifying is a great way to understand how external libraries or scripts work by making their structure transparent.
