String to Encode (UTF-8):

Encoded String (Base64):

About

This utility provides a robust solution for encoding strings into Base64 format, with full support for UTF-8 characters. Base64 is a common encoding scheme used to represent binary data in an ASCII string format, making it suitable for transmission over mediums that only support text. The encoding process involves first converting the input string into its UTF-8 byte representation using the `TextEncoder` API. These bytes are then transformed into a binary string, which is finally encoded into Base64 using the `btoa()` (binary to ASCII) JavaScript function. This client-side implementation ensures that all encoding operations are performed securely within the user's browser, without any data being sent to a server.
