Case Converter
Instantly convert any text between uppercase, lowercase, title case, sentence case and more.
What Is the Case Converter?
The Case Converter transforms your text between six common capitalization styles: UPPERCASE, lowercase, Title Case, Sentence case, aLtErNaTiNg case, and InVeRsE case. It's a fast fix for text that was typed with the wrong caps lock setting, a quick way to format headlines and titles correctly, or a fun tool for generating stylized, alternating-case text for social posts.
Writers, students, and social media managers use case converters constantly — correcting accidentally-shouted all-caps text, formatting article titles into proper Title Case, or making sure the first letter of every sentence is capitalized without manually fixing each one. Everything updates live as you type or switch case styles, so you can compare options instantly before copying your final result.
