Pick a random letter from A–Z instantly with our free, cryptographically fair letter generator.
The Random Letter Generator picks letters from the English alphabet with true cryptographic fairness, so every draw from A to Z is completely unpredictable and free from the patterns of ordinary pseudo-random code. Instead of typing letters and second-guessing whether you subconsciously favored a familiar one, you get an impartial, evenly weighted result in a single click. Choose one letter or a whole sequence, switch between uppercase and lowercase, restrict the pool to vowels or consonants, and decide whether repeats are allowed. Everything runs locally in your browser using the Web Cryptography API, which means the outcome is generated instantly with zero network latency and nothing about your activity is ever sent to a server.
Turn random ideas into high-performing content. Try: Viral Topic Generator
Kick off Scattergories, Categories, or a quick spelling round by drawing a starting letter that nobody at the table can influence. It is the fair, tamper-proof way to decide which letter every player must build their words around this turn.
Teachers and parents can pull a random letter for phonics drills, letter-of-the-day activities, and handwriting practice. Restrict the pool to vowels or consonants to focus a lesson, or draw several letters to build simple word-blending exercises for early readers.
Writers, brand namers, and quiz makers use a random starting letter to break creative blocks. Draw a letter and challenge yourself to invent a character name, a company name, or a story prompt that begins with it — a fast way to spark fresh ideas.
Assign people to groups, pick an order, or run an icebreaker where everyone shares something starting with the drawn letter. Because the selection is cryptographically random, no one can claim the outcome was rigged in anyone's favor.
The generator reads random bytes directly from your operating system's entropy source through the browser's crypto module, then maps them onto the alphabet. To keep every letter equally likely, we discard any raw value that would fall into an incomplete final block before applying the modulo operation — this eliminates modulo bias, the subtle skew that makes naive random code favor lower letters. When duplicates are disabled, we use a partial Fisher–Yates shuffle so each unique letter still has an identical chance of being drawn.
