Morse Code TranslatorTranslate text to Morse code and Morse code back to text. Supports letters, numbers and punctuation in International Morse Code.
Binary Translator: Text to BinaryConvert text to binary code and binary back to text. Uses 8-bit bytes with UTF-8, so it handles ASCII and every other character.
Hex Translator: Text to HexadecimalConvert text to hexadecimal bytes and hex back to text using UTF-8. Useful for reading hex dumps and encoding strings.
Base64 Encoder and DecoderEncode text to Base64 or decode Base64 back to text, with full UTF-8 support and a URL-safe variant.
Text to ASCII and Unicode ConverterConvert text to ASCII codes and Unicode code points in decimal and hex, or turn a list of character codes back into text.
Caesar Cipher Encoder and SolverEncrypt or decrypt text with a Caesar shift cipher. Shows all 25 possible shifts so you can solve a cipher without knowing the key, including ROT13.
Letter to Number Converter (A1Z26)Convert letters to their alphabet position numbers, where A is 1 and Z is 26, or convert numbers back to letters.
Hex CalculatorAdd, subtract, multiply and divide hexadecimal, binary, octal or decimal numbers, and apply bitwise AND, OR and XOR. Results in all four bases.
Chmod CalculatorBuild Unix file permissions by ticking read, write and execute for owner, group and others. Get the octal number, symbolic notation and chmod command.
IEEE 754 Floating Point ConverterConvert a decimal number to its IEEE 754 single and double precision representation: sign, exponent and mantissa bits, hex value and the exact stored number.
