Frequently asked questions
What is the difference between Title Case and Sentence case?
Title Case capitalises the first letter of every word (e.g. 'The Quick Brown Fox'). Sentence case capitalises only the first letter of each sentence (e.g. 'The quick brown fox jumps.').
What does iNVERSE case do?
iNVERSE swaps the case of every letter — uppercase becomes lowercase and vice versa, character by character.
Does Title Case handle small words like 'and' or 'of'?
This tool uses simple Title Case which capitalises every word. For AP- or Chicago-style headlines that lower-case articles and short prepositions, you may need to adjust manually.
Are accented characters and non-Latin scripts supported?
Yes — case conversion uses JavaScript's built-in Unicode-aware toUpperCase/toLowerCase, so French, Spanish, German, and other Latin-script languages work correctly.
