What is Base64 Decoding?

Base64 decoding reverses the Base64 encoding process, converting a Base64 string back into original binary data or text. Each Base64 character represents 6 bits.

How Base64 Decoding Works

1. Remove any padding characters (=). 2. Convert each Base64 character to its 6-bit value. 3. Concatenate all 6-bit values into a binary stream. 4. Split the binary stream into 8-bit bytes. 5. Decode bytes using the selected character encoding. Example: "SGVsbG8=" → "Hello"

Common Use Cases

• Decoding Base64-encoded API responses. • Extracting embedded images from data URIs. • Reading MIME-encoded email content. • Decoding JWT token payloads. • Converting Base64 config values to readable text.
