Base64 Encoder/Decoder

A Base64 tool converts text to Base64 and back again. Paste text into the encode side to get the encoded string, or paste a Base64 string into the decode side to recover the original. Base64 exists so that data can travel through systems built for plain text, which is why it shows up in email attachments, data URLs and API tokens. It is an encoding rather than encryption, so it hides nothing from anyone who bothers to decode it.
