How Does It Work?
|Removes Comments||Removes comments in the code that describe what the code is doing.|
|Compression||Compresses the code by removing whitespace and line breaks.|
|Obfuscation||Renames variables into shorter names to make the code more compact.|
|Source Maps||Maps the minified code back to the original code for debugging.|
- When a website has slow page loading time.
- When a website is hosted on a slow server.
- When a website has a large number of users.

Misconceptions and FAQs
Misconception: Minifying code is enough for performance optimization.
While minifying your code is a crucial step in optimizing your website’s performance, it is not the only step. Other steps, such as optimizing images, reducing server response times, and enabling caching, are also essential.
FAQ 1: Will minifying my code affect my website’s functionality?
No, minifying your code should not affect the functionality of your website. The tool should only remove characters that are not required to execute the code. The structure and functionality of the code should remain the same.
FAQ 2: Can I reverse the minification process?
Yes, reverse minification is possible by using Source Maps. Source Maps map the minified code back to the original code for debugging purposes.
