About Base64 Encoder/Decoder
Base64 is an encoding scheme that converts binary data into ASCII text, making it safe to transmit over text-based protocols like HTTP and email. It is widely used for embedding images in HTML/CSS (data URIs), encoding API tokens, and storing binary data in JSON.
This tool supports encoding plain text strings (including Unicode/UTF-8 characters) to Base64 and decoding them back. All processing happens entirely in your browser — your data never leaves your device.
