About the Base64 Encoder/Decoder
Switch between Encode and Decode, paste your text or Base64 string, and the output updates live. UTF-8 text — including emoji and accented characters — is fully supported in both directions. Enable URL-safe mode if you need the result to drop directly into a URL query parameter without additional escaping.
