Why use our Case Converter?
Retyping text just to fix its capitalisation is a waste of time. This free Case Converter changes your text to any style in one tap — UPPERCASE, lowercase, Title Case, Sentence case, plus developer styles like camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE. There are even fun ones like aLtErNaTiNg and InVeRsE case.
It's perfect for writers fixing accidental caps lock, students formatting headings, and developers naming variables. Everything runs in your browser — fast, free, no sign-up, and your text never leaves your device.
How do I convert text case?
Type or paste your text, then tap a case button. The text updates instantly and you can copy it.
What is the difference between Title Case and Sentence case?
Title Case capitalises the first letter of every word; Sentence case only capitalises the first letter of each sentence.
Is my text private?
Yes — everything is processed locally in your browser and is never uploaded.
