What is Image to Base64?
Converting an image to Base64 produces a self-contained data URI that can be embedded anywhere a URL is accepted: an HTML <img src>, a CSS background-image, an SVG xlink:href, or a JSON field. Embedding images as Base64 eliminates the need for a separate HTTP request per image, which is useful for email HTML templates, single-file HTML exports, UI component libraries, and reducing round trips in REST APIs. The tradeoff is that Base64-encoded images are approximately 33% larger than their binary equivalents, so this technique is most practical for small images like icons, logos, and thumbnails.
