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.
