What is Case Converter?
A case converter changes the capitalisation of text without retyping it. Paste a sentence, a headline or a whole paragraph and it shows the result in nine styles at once: UPPERCASE, lowercase, Title Case, Sentence case, aLtErNaTiNg, camelCase, PascalCase, snake_case and kebab-case. Writers use it to fix text typed with caps lock on, editors use it to format headlines, and developers use it to turn plain phrases into variable names, file names and web addresses. One paste replaces a tedious manual edit and keeps capitalisation consistent across emails, documents, social posts and code.
How Does It Work?
When you type or paste, Vebliy applies nine small conversion rules to your text at the same time and shows each result in its own card. The simple styles use your browser's built-in upper and lower case functions. Title Case lowercases the text, then capitalises every word except short joining words such as of, and or the, always keeping the first and last word capitalised. Sentence case capitalises the first letter after each full stop, question mark or line break. The programming styles split your text into words, even when it already contains camel case, and rejoin them. Everything runs in your browser, so nothing you enter is uploaded or stored.

Frequently Asked Questions
What is the difference between Title Case and Sentence case?
Title Case capitalises the main words of a phrase, like a book title. Sentence case capitalises only the first word of each sentence and the pronoun I, which suits normal paragraphs.
Which style guide does Title Case follow?
It uses a common rule close to AP style: short articles, conjunctions and prepositions stay lowercase unless they open or close the title. Guides differ on longer words, so check yours for formal publishing.
Can I convert several lines at once?
Yes, and your line breaks are kept. The programming styles treat each line separately, so a list of phrases becomes a list of variable names.
Why does Sentence case remove capitals from names?
It lowercases everything first, so names and acronyms such as London or NASA lose their capitals. Restore those few words by hand after copying.
Is my text sent anywhere?
No. Every conversion runs locally in your browser. Your text is not uploaded, stored or logged, and it disappears when you refresh the page.
