Base64 encoding translates binary or textual data into a safe ASCII string format. This is incredibly useful for transmitting data over media that are designed to deal exclusively with textual data (like JSON payloads or URLs). Our converter works entirely in your browser using secure APIs, ensuring your sensitive data is never sent to a server.
