About this tool
This page opens the converter in Base64 decoding mode — paste a Base64 string and get the original text back, or download it as a file if the data turns out to be binary.
Base64 decoding reverses the 64-character encoding used in data URIs, email attachments and API payloads; you need it whenever you receive Base64 and want the readable original.
The full tool also encodes to Base64, hex and binary — everything runs locally in your browser, so tokens and private payloads never touch a server.
Example. The text Hi encoded as Base64 is SGk=.
