What is Image to Base64 Converter?
An image to Base64 converter encodes image bytes as text.
Raw Base64 contains the encoded data; a data URI adds a media type prefix such as data:image/png;base64, so it can be used in HTML or CSS. SlapMyWeb's converter uses the browser FileReader API and provides both formats for copying. Base64 text is larger than the original binary file, so it is generally most useful for small assets or data exchange where text encoding is needed.
