What is Image to Base64 Converter?
A Base64 data URL embeds the binary content of an image directly into HTML or CSS. This eliminates the HTTP request for small icons and graphics, which can improve perceived load time. The tradeoff: Base64 encoding inflates file size by roughly 33%, so it's best for icons under 5 KB.
