What it's for
This tool converts the capitalization of any text — useful for fixing text accidentally typed with Caps Lock on, standardizing titles, preparing text for social media, or quickly formatting names and lists.
Difference from the programming case converter
If you're looking to convert code identifiers between camelCase, snake_case, kebab-case and PascalCase, use the Case Converter instead — this tool works with ordinary text (sentences, titles, paragraphs), not variable names.
Available modes
UPPERCASE: all letters capitalized. lowercase: all letters in lower case. Title Case: capitalizes the first letter of every word, handy for titles. Sentence case: capitalizes only the first letter of each sentence, like normal running text. tOGGLE cASE: inverts the capitalization of every individual letter — good for text effects or messing with someone in chat.
Frequently asked questions
Does this tool handle accented characters correctly?
Yes, it preserves accents and other special characters normally, only changing letter capitalization.
What's the difference between this and the "Case Converter" tool?
This tool converts ordinary text (UPPERCASE, lowercase, Title Case, etc). The Case Converter is for programming, converting between camelCase, snake_case, kebab-case and PascalCase.
Does Title Case capitalize articles and prepositions?
The Title Case mode capitalizes the first letter of every word, including articles and prepositions — if you need finer editorial rules (keeping small words lowercase), adjust manually afterward.
Is my text saved anywhere?
No. All conversion happens in your browser — the text is never sent to any server.
