Base64 Utility Guide
Base64 encoding is a widely used binary-to-text encoding scheme. It translates binary data into a set of ASCII characters, specifically including A-Z, a-z, 0-9, +, and /. This makes it incredibly useful for transferring files through systems that only support text, such as embedding images in HTML or CSS files.
How does it help SEO?
By using Base64 strings for small icons and assets, you reduce the number of HTTP requests your website needs to load. Faster loading times lead to better Core Web Vitals, a critical ranking factor in Google's search algorithm.
