Quick Presets
This tool generates random letters from the English alphabet in an instant. Choose how many letters you need (1 to 26), pick a case style, and decide whether repeats are allowed. Hit Generate — or just tweak any setting — and your letters appear immediately. One click copies the result to your clipboard.
The generator uses the browser's built-in Math.random() to select letters. For no-repeats mode it performs a Fisher-Yates shuffle on the 26-letter alphabet and takes the first N letters — guaranteeing an unbiased random sample. All processing happens in your browser; no data is sent to a server.

A random letter generator picks letters from the alphabet at random. You control how many letters to generate (1–26), the case (uppercase, lowercase, or mixed), and whether the same letter can appear more than once. Common uses include games, education, creative writing prompts, and sampling exercises.
When "No Repeats" is enabled, each generated letter can only appear once in the result — similar to drawing letters from a bag without replacement. Because there are only 26 letters in the alphabet, the maximum count is capped at 26 when this option is on.
Mixed case means each letter is independently and randomly assigned to either uppercase or lowercase. The result is a random blend like "aKmBzQ". Useful for random passwords seeds, creative typography, or games.
The generator uses the browser's built-in Math.random(), which is a pseudo-random number generator (PRNG). It produces statistically unpredictable results suitable for games, education, and everyday tasks. It is not cryptographically secure — for cryptographic purposes use a dedicated CSPRNG.
Common uses: spelling games and activities for kids, Scrabble-style tile drawing, random word-start prompts for creative writing, classroom alphabet games, letter-frequency sampling, generating placeholder text seeds, and board game mechanics.
Yes. Set the count to 26, enable "No Repeats", and hit Generate. This produces a full random shuffle of the alphabet — every letter exactly once in a random order.
