What is Base64 Image Encoding?
Base64 encoding is a way to represent binary data (like an image) as an ASCII string. In web development, this allows you to embed an image directly inside an HTML document or a CSS file using a "Data URI" instead of linking to an external file.
Pros and Cons
Advantages
- Reduces HTTP requests, speeding up initial page load time.
- Prevents "flashes" of unstyled content if icons are loaded lazily.
- Great for tiny icons, placeholders, and small graphics.
Disadvantages
- Increases file size by ~33%.
- Blocks parsing while the browser downloads the CSS/HTML file.
- Cannot be cached independently of the HTML/CSS file.
Best Practice: Only use Base64 encoding for very small images (under 5KB) where the overhead of a new HTTP request outweighs the increased payload size.
