Direct answer

What Base64 Encoder and Decoder does

Base64 encoding represents bytes as text for systems that need a text format. Base64 decoding reverses that representation. Base64 does not provide confidentiality: anyone with the encoded value can decode it without a secret key.

Output

What you receive

The tool returns a text result. Check the result before you use it in another system.
