About Image to Base64 Encoder

Embedding small graphical assets directly into your stylesheets or JSON payloads can significantly reduce external HTTP requests and speed up web performance. This utility leverages your browser's native `FileReader` API to read your local image files and compile them into valid Base64 Data URI strings. Because the file processing happens securely on your own device, you can safely encode proprietary assets without risking them being intercepted or stored on third-party servers.
