What is Base64 Encoder/Decoder?
Base64 is a binary-to-text encoding scheme that represents binary data as printable ASCII characters. It's commonly used to embed images in HTML/CSS, encode authentication credentials in HTTP headers, transmit binary data through text-only channels like email, and encode data in URLs. Our free Base64 tool encodes and decodes text and files entirely in your browser — nothing is sent to a server.
