Base64 Encoder / Decoder

Base64 is a binary-to-text encoding scheme that represents binary data using a set of 64 printable ASCII characters. It is widely used in email, HTTP basic authentication, data URIs, and API payloads. Use this free tool to encode any text string to Base64 or decode a Base64-encoded string back to its original form — all processing happens locally in your browser with no data sent to any server.
