Common Questions About JS Minification
Will minifying my code break it?
No. Minification only removes "useless" characters for the computer, like spaces and comments. Your actual logic remains exactly the same.
Why is minification important for SEO?
Google used PageSpeed as a ranking factor. Smaller JS files load faster, leading to a better user experience and potentially higher search rankings.
What characters are removed?
Spaces, tabs, newlines, and both single-line and multi-line comments are stripped to save every possible byte.
Is there a file size limit?
Since the processing happens in your browser, the limit is only restricted by your computer's RAM. It can handle very large scripts easily.
