Open Sentence Case Converter →Text arrives in the wrong case constantly: a heading typed with caps lock on, an all-lowercase paste, a title that needs proper capitalization. Retyping it is slow and introduces typos. A case converter transforms the whole block at once, so a shouty sentence becomes normal Sentence case or a heading becomes clean Title Case without touching the words themselves.
UPPERCASE and lowercase are self-explanatory. Title Case capitalizes the significant words, which suits headings and names, while Sentence case capitalizes only the first letter, which is right for body copy and rescuing text typed in all caps. A dedicated sentence-case tool handles that last job cleanly. Everything runs locally, so pasted text is never transmitted.
