These tools handle the conversion between image files and Base64-encoded data URIs — a common pattern for embedding images directly into HTML, CSS, or JSON without referencing external files. Encode an image file to Base64, decode a Base64 string to preview the image, or fetch an image from a remote URL and encode it inline.
A Base64 image is an image encoded as a text string using the Base64 format, often prefixed with a data URI (e.g., data:image/png;base64,...). It can be used directly in HTML src or CSS url() without a separate file.
Base64 images are ~33% larger than the original binary file and cannot be cached separately by the browser. Use them for small icons or inline email images; for larger images prefer external files.
Yes. Encoding and decoding runs entirely in your browser. Image data is not uploaded to any server.
