About Base64 Image Encoding
Base64 encoding converts binary image data into ASCII text format, making it possible to embed images directly in HTML, CSS, or JSON. This is useful for small images, icons, or when you need to include images inline without separate file references.
Pros: Self-contained, no external requests, works in any text context
Cons: ~33% larger than original, not cached separately
Best for: Small images (<10KB), icons, inline SVGs, email templates
