Embed Images with Base64

Base64 encoding allows you to represent binary image data as an ASCII string. This lets you embed images directly into HTML files (using <img src="data:image...">) or CSS files (background-image).

Pros & Cons

  • Pro: Reduces HTTP requests (fewer server round-trips).
  • Pro: Single-file portability (email templates, offline pages).
  • Con: Increases file size by ~33%.
  • Con: Blocks browser caching of individual images.

Best Use Cases

Use Base64 for tiny icons, logos, or background patterns. Avoid converting large photographs as they will bloat your HTML significantly.
