When to use Base64 for Images?

Reducing HTTP Requests

For tiny assets like icons or decorative separators, embedding them as Base64 in your CSS can speed up the "Initial Render" by removing extra file fetches.

Email Templates

Email clients often block external images. Inlining graphics as Base64 ensures your template looks perfect even when the user is offline or has images disabled.

Data Portability

If you're sending a JSON object that needs to include a small user avatar or preview, Base64 allows you to keep the data self-contained.
