Minify JavaScript

What is JavaScript Minify & Pretty Print?

JavaScript Minify and Pretty Print are processes used to format JavaScript code. Minification reduces file size by removing unnecessary characters (like whitespace and comments), while Pretty Printing adds proper indentation and formatting to make the code more readable.

How to Use This Tool?

• Enter JavaScript: Paste your JavaScript code into the input textarea.
• Minify: Click the "Minify" button to remove unnecessary whitespace and comments.
• Toggle Format: Use "Toggle Minify" or "Toggle Pretty" button to switch betweenthe minified and pretty-printed JavaScript.
• Copy/Download: Use the "Copy" button to copy the processed JavaScript to your clipboard, or the "Download" button to save it as a .js file.
• Upload/Fetch: You can upload a local JavaScript file or fetch JavaScript from a URL.

Why Should I Minify My JavaScript?

Minifying JavaScript reduces the file size, which leads to faster page load times, improved website performance, and reduced bandwidth usage. This is especially important for mobile users or those with slower internet connections.

When Should I Use Pretty Print?

Pretty Printing is useful when you need to read, debug, or modify the JavaScript code. It makes the code structure more visible and easier to understand, which is particularly helpful during development or when reviewing code.

Does Minification Affect My Code's Functionality?

When done correctly, minification should not affect your code's functionality. It only removes unnecessary characters and may rename some variables. However, it's always a good practice to test your minified code thoroughly before deploying it.

Are Comments Removed During Minification?

Yes, most JavaScript minifiers remove comments to further reduce file size. If you need to keep certain comments (like license information), you should use special comment syntax that the minifier will preserve.
