About Random Letter Generator

This random letter generator picks letters from the English alphabet using cryptographically secure randomness. Filter by vowels or consonants, choose uppercase, lowercase, or mixed case, and set a custom separator. Useful for word games, teaching exercises, password creation, and randomized testing.

Frequently Asked Questions

How are the letters generated?
Letters are generated using crypto.getRandomValues(), which provides cryptographically secure random numbers. This ensures truly unpredictable letter selection.
Can I generate only vowels or consonants?
Yes. Use the filter buttons to switch between All Letters, Vowels Only (a, e, i, o, u), or Consonants Only (all other letters).
What case options are available?
You can generate uppercase letters only, lowercase letters only, or mixed case where each letter is randomly uppercase or lowercase.
How many letters can I generate at once?
You can generate between 1 and 100 random letters at a time using the count slider or number input.
Is my data sent to a server?
No. All letter generation happens entirely in your browser. No data is sent to any server.
