Character Encodings

ASCII table with a mini converter, text-to-binary/octal/dec/hex converter, Base64 encode and decode plus a cryptographically secure password generator.

ASCII TableComplete ASCII table 0..127 with decimal, hex and character. Search jumps to a unique hit on any input (e.g. 65 or A) and shows dec, hex, octal, binary plus a mnemonic explanation for control characters.
ConverterConverts text into binary, octal, decimal or hex and back. With separator choice, fixed-width padding (8/3/2 digits) and a per-character codepoint preview.
Base64Base64 encoder and decoder in the browser. Handles umlauts, emojis and arbitrary Unicode cleanly via UTF-8 and distinguishes charset errors from UTF-8 decode errors.
Password GeneratorGenerate passwords with lowercase, uppercase, digits and symbols. Up to 128 characters long, cryptographic random source (crypto.getRandomValues), strength and entropy display.
