About this tool

Generate random strings with full control over character sets, length, and formatting. Choose from 11 character sets: alphanumeric, alphabetic, lowercase, uppercase, numeric, hexadecimal (lower and upper), Base64, URL-safe, binary, and all characters. Six presets generate common formats instantly: API keys (sk_live_ prefix, 32 chars), tokens (64-char hex), session IDs (24-char URL-safe), verification codes (6-digit numeric), slugs (8-char lowercase), and hex colors (#XXXXXX). Add custom prefixes and suffixes, insert separators (dash, underscore, dot, space) every 4 characters, and generate up to 50 strings at once. All generation uses the Web Crypto API for cryptographic randomness.
