How does this tool work?
Base64 is a method for encoding binary data into a string consisting only of ASCII characters.
Enter your text or Base64-encoded data into the text field. You can instantly encode or decode the content using the corresponding buttons. This is particularly useful for data transmission in web interfaces or embedding small files.
