What is Random Letter and Character Generator?
Use this random letter generator to get random characters drawn from the character types you choose (uppercase, lowercase, numbers, symbols). Useful for quick randomization tasks, test data, or picking a random letter for a game.

How It Works
Each character is drawn from the character sets you've enabled (uppercase, lowercase, numbers, symbols) using crypto.getRandomValues(), the browser's cryptographically secure random source. Results aren't predictable from a previous batch, even though this tool is meant for quick everyday randomization rather than generating secrets.
Common Use Cases
Picking a random letter or symbol for a game, raffle, or classroom activity.
Generating quick single-character test input for form validation or edge-case testing.
Sampling characters from a specific set (e.g. only uppercase and numbers) when you need randomization but not a full password.
