ABOUT THIS TOOL
What is the Base64 Encoder & Decoder?
Base64 represents binary or text data using a restricted set of printable characters. Developers commonly see it in data URLs, API payloads and encoded configuration.
How the result is calculated
Encoding converts Unicode text to UTF-8 bytes before Base64 conversion. Decoding reverses the process. Base64 is an encoding, not encryption.
Practical example
The text Tool88 becomes VG9vbDg4 in Base64. Anyone can decode it, so never use Base64 to protect secrets.
