Base64 encodes binary image data into text format that can be embedded directly in HTML, CSS, or JSON without needing a separate file request.

When should I use Base64 images?

Base64 is useful for small images (under 10KB) where reducing HTTP requests matters. For larger images, standard file URLs load faster.

What is Base64?

Base64 is an encoding scheme that converts binary data into ASCII text. It's commonly used to embed images directly in HTML, CSS, or JSON without needing separate image files.

Common Use Cases

CSS: Embed small icons as background-image data URIs
HTML: Inline images using <img src="data:...">
Email: Embed images in HTML emails
APIs: Send images in JSON payloads

Size Considerations

Base64 encoding increases file size by approximately 33%. It's best suited for small images (icons, thumbnails) where the overhead of additional HTTP requests outweighs the size increase.
