Numbers in words and in other bases
The number to words converter writes figures as words, ordinals or cheque amounts, and the number base converter shows any whole number in binary, octal, decimal, hexadecimal and base 36 at once.
Encoders, Ciphers & Translators
Convert text into codes and back again. Each tool detects the direction automatically where it can, and the ciphers show every option so you can decode messages without knowing the key.
EncodersBase64 Encoder and DecoderEncode text to Base64 or decode it back.EncodersBinary Code TranslatorText to binary and binary to text.EncodersHex to Text ConverterHexadecimal to text and text to hex.EncodersMorse Code TranslatorTranslate to and from Morse code, with sound.EncodersCaesar Cipher Encoder and DecoderShift letters by any amount to encode or decode.EncodersROT13 Encoder and DecoderRotate letters 13 places.

Encoding is not encryption
Base64, binary, hex and URL encoding change how data is written, not who can read it. Anyone with the same tool can reverse them, so they are for transport and compatibility, not secrecy. The Caesar and ROT13 ciphers are historical puzzles that can be broken by trying all 25 shifts, which the Caesar tool does for you. For anything sensitive, use real encryption software.
Translators for people, not machines
The Morse code translator follows the international standard and can play the code as sound. The NATO alphabet and letter-name spellers help you read names, codes and addresses over the phone without confusion, and the Pig Latin translator is simply for fun.
