Hex, Base32, Base58, Base64, CBOR, HTML entities, URL encoding and JWT decoding — text and files, all in your browser.
"File → Hex" reads the chosen file and writes its encoded form into the box above. "Hex → File" decodes the text in that box and downloads it as a file.
"File → Base32" reads the chosen file and writes its encoded form into the box above. "Base32 → File" decodes the text in that box and downloads it as a file.
"File → Base58" reads the chosen file and writes its encoded form into the box above. "Base58 → File" decodes the text in that box and downloads it as a file.
"File → Base64" reads the chosen file and writes its encoded form into the box above. "Base64 → File" decodes the text in that box and downloads it as a file.
Supports the common CBOR types: integers, floats, strings, booleans, null, arrays and maps — enough to round-trip typical JSON data. Byte strings decode as hex.
Decodes the header and payload only — this does not verify the signature.
