About Image to Base64

Image to Base64 encodes a picture into a Base64 data URI for embedding in HTML, CSS, or JSON. Developers searching "image to Base64", "data URI image", or "Base64 encode image" need inline assets without extra HTTP requests for tiny icons.

Upload an image and copy the Base64 output. Large photos bloat HTML - reserve Base64 for small icons and simple graphics.

Caching and maintainability are often better with normal image files. Use data URIs deliberately, not for every asset.
