How to convert text case
Enter or paste your text into the editor. Click Uppercase to convert every letter to capitals, Lowercase for all small letters, or Title Case to capitalize the first letter of each word. The result replaces the editor content instantly so you can copy it.
Conversion happens entirely in your browser. No text is uploaded to a server, keeping passwords, code snippets, and personal messages private.
