Minification is the process of removing unnecessary characters — such as whitespace, line breaks, and comments — from a website’s CSS, JavaScript, and HTML files, reducing their file size without changing their actual functionality.
Smaller, minified files load faster, directly supporting improved page speed and Core Web Vitals performance, particularly for sites with large amounts of custom or unoptimized code accumulated over time.
Minification is typically automated through build tools or caching plugins rather than done manually, making it a relatively easy, low-risk technical optimization to implement on most modern websites.
Minification is a standard optimization included in our Technical SEO service.
