Base64 Converter questions
Is Base64 encryption?
No. Base64 is a reversible encoding format and provides no confidentiality. Anyone can decode it without a secret key.
Why does Base64 output look longer than the original text?
Base64 represents binary data using a restricted text alphabet, which typically increases the encoded size by about one third.
