Yes. Choose lowercase or mixed case before generating the result.
Random Letter Generator
Generate random letters with case and duplicate options.
Calculations happen locally. We do not send your values to our server.
Example
Generating 10 uppercase letters may produce a result such as QMTABZKCRP, entirely inside the browser.
Calculation method
Secure random integers select indexes from uppercase, lowercase, or combined Latin alphabets; unique mode prevents repeated characters.
Important notes
The tool uses unaccented English letters A–Z. Unique requests cannot exceed 26 letters per case or 52 in mixed mode.
Frequently asked questions
Why can unique mode reject a large count?
There are only 26 characters in one case and 52 distinct characters in the mixed alphabet.
Does this generate words?
No. It produces independent random letters without language or pronunciation rules.
