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.
