Converts text into hexspeak — words and phrases spelled using only hexadecimal characters (0-9, A-F), replacing letters with hex-compatible lookalikes.
Hexspeak is a novelty form of communication where words are spelled using only the characters available in hexadecimal notation: 0-9 and A-F. Letters that don't exist in hex are substituted with visually similar hex digits — for example, O becomes 0, I becomes 1, S becomes 5, and T becomes 7. Classic examples include 0xDEADBEEF, 0xCAFEBABE, and 0xBADF00D.
The translator converts your English text into hex-compatible equivalents by substituting non-hex letters with their closest numeric lookalikes. Some words translate perfectly (like FACE, DEAD, or CAFE), while others require creative substitution. The result looks like valid hexadecimal values while still being readable as English words.
Standard replacements include: O→0, I→1, S→5, T→7, G→6, R→2, Z→2, L→1. Some substitutions are more liberal depending on the style chosen, allowing for greater vocabulary at the cost of strict hex purity.

Hexspeak uses only the 16 hexadecimal characters: the digits 0-9 and the letters A, B, C, D, E, and F. All other letters must be substituted with visually similar hex characters (like S→5, O→0, I→1) or the word cannot be fully converted.
Many are used as magic numbers in software: 0xDEADBEEF (used as a debug marker), 0xCAFEBABE (Java class file identifier), 0xBADF00D (indicates uninitialized memory in some systems), 0xFEEDFACE (Mach-O binary format), and 0xC0FFEE (used in various debug contexts).
Words containing letters like W, M, K, or X have no obvious hex lookalike in strict mode. In liberal mode, more creative substitutions are attempted (like W→3 or K→C), but some combinations still don't produce readable results. The translator will use the closest approximation available.
Yes — every hexspeak word is a valid hexadecimal number that can be converted to a decimal value. For example, 0xDEAD equals 57005 in decimal, and 0xCAFE equals 51966. This dual nature as both readable text and valid numbers is what makes hexspeak unique.
