Encoder and decoder
Base64, URL, hex, HTML entities and Unicode escapes, both directions, in your browser. Built for the moment a payload in a log line has been encoded twice and you need to see what it actually says before deciding whether to wake anyone up.
Everything you type stays in this tab. Share copies a link, never your inputs, unless the tool says it encodes them in the URL.
Decode repeatedly keeps unwrapping while each layer still decodes to printable text, up to eight rounds, and shows the chain. Nothing here executes what it decodes.
