Convert text between UPPERCASE, lowercase, Title Case, Sentence case and iNVERTED case.
Retyping a paragraph because it came in the wrong case is wasted work — and pressing Caps Lock by accident is how half of those paragraphs are born. This converter fixes case in one click: everything up, everything down, Title Case for headlines, Sentence case for normal prose, and inverted case to rescue text typed with Caps Lock on.
Title Case capitalizes the first letter of each word — the convention for English headlines and button labels. Sentence case capitalizes only the first letter of each sentence, detecting sentence endings at periods, exclamation and question marks. Both handle accented letters correctly: "água" becomes "Água", not "áGua", because the conversion uses Unicode-aware functions rather than ASCII tricks.
The text stays on your device — nothing you paste is transmitted or stored, which makes the tool safe for unpublished drafts and confidential copy. For social media styling beyond case, pair it with the character counter to keep your text inside each platform's limits.
Yes. Conversion uses Unicode-aware string functions, so á, ç, ã and any accented letter change case correctly.
Title Case Capitalizes Every Word, as in headlines. Sentence case capitalizes only the first word of each sentence, as in normal writing.
It swaps the case of every letter — the classic fix for text typed with Caps Lock accidentally on, and the source of the sarcastic mEME cASE.
No. The conversion runs in your browser and the text is discarded when you leave the page.
