How to Use the Text Case Converter
Type or paste your text into the input field, then click any conversion button to instantly transform the case. The tool supports eight common text case formats used in writing and programming.

Frequently Asked Questions
What is the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word. Sentence case only capitalizes the first letter of each sentence, leaving the rest lowercase.
Does this tool work with non-English text?
UPPERCASE and lowercase work with any language that has case distinctions (Latin, Cyrillic, Greek, etc.). Programming cases like camelCase and snake_case work best with ASCII text.
Is my text sent to a server?
No. All conversion happens entirely in your browser. Nothing is uploaded or stored anywhere.
