What Is Code Minification?
Code minification is the process of removing unnecessary characters (whitespace, line breaks, comments) without changing the functionality. This reduces file size and improves page load times.
Why Should You Minify Your Code?
Smaller files download faster, which improves user experience and SEO performance. Google considers page speed as a ranking factor. Minification can reduce CSS and JavaScript file sizes by 20% to 60%.
Frequently Asked Questions
Does minification affect how the code works?
No. Minification only removes characters that do not affect code execution. The result is functionally identical to the original.
What is the difference between minifying and formatting?
Minifying compresses code by removing spaces and line breaks. Formatting does the opposite: it takes compressed code and adds indentation and line breaks to make it human-readable.
