Image to Base64

Embedding images as Base64 data URIs eliminates an HTTP request. Instead of the browser fetching a separate image file, the image data is inlined directly in your HTML or CSS. For small images (icons, logos under ~10KB), this can improve page load performance by reducing round trips to the server.

The trade-off is size: Base64 encoding increases data by roughly 33%, and the string can't be cached separately from the HTML/CSS file. For large images, a regular file reference with proper caching is almost always better. The sweet spot is small UI icons, simple logos, and placeholder images.

Common use cases include embedding images in HTML emails (where external images are often blocked), single-file HTML documents, CSS backgrounds for tiny UI elements, and offline-capable web apps. This tool generates the Base64 string plus ready-to-use HTML <img> and CSS background-image snippets.
