Use this encoder when a receiving system, file format, protocol, puzzle, or historical cipher explicitly requires the named representation and its alphabet or key convention is known.

Text

Required string input.

Encode UTF-8 text as canonical Base64 text. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Base64

The resulting base64 returned as a string.

• Encoding changes representation, not trustworthiness or meaning. Alphabet variants, padding, line wrapping, character encoding, byte order, unsupported characters, and malformed Unicode can affect interoperability; classical ciphers and checksums do not provide modern confidentiality or authenticity.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Round-trip representative values through the matching decoder and verify published test vectors where available. Use authenticated encryption for security and a cryptographic hash or MAC when integrity against an adversary is required.

• Base122 Encoder

  Encode UTF-8 text as Base122 artifact text, avoiding null, newline, carriage return, quote, ampersand, and backslash bytes.

• Base32 Encoder

  Encode UTF-8 text as RFC 4648 base32 using letters A-Z and digits 2-7 with padding.

• Base58 Encoder

  Encode UTF-8 text as Base58 using the Bitcoin alphabet.
