In today’s fast-paced digital world, website speed matters more than ever. Whether you’re a developer, SEO expert, or blogger, optimizing your website’s code can make a significant difference. One of the simplest ways to speed up your site is by using an HTML minifier—a tool that compresses your HTML files by removing unnecessary spaces, comments, and line breaks.
