Image to Base64

Convert an image to a Base64 data URI.

How image to Base64 works

Your browser reads the file's raw bytes and writes them as Base64 text. Adding the prefix data:image/png;base64, makes a "data URI" that can be used directly as an <img src> or CSS url() without a separate file request.

Base64 is about 33% larger than the original file, so it is best for small images such as icons. The image never leaves your device.

Processed locally in your browser — your input is never uploaded.
