Case Converter

UPPERCASE, lowercase, Title Case, camelCase and more.

Case Converter transforms text into upper, lower, sentence and title case, plus the programming conventions: camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and dot.case. Title case follows real style-guide rules about short words rather than blindly capitalising everything. The conversion runs in the page itself, so nothing you paste is uploaded.

Questions about Case Converter

How is title case decided?
Following the AP and Chicago conventions: capitalise the first and last word and every significant word, but leave articles, short prepositions and coordinating conjunctions lowercase in the middle. "The Rise of the Machines", not "The Rise Of The Machines".
Does it handle accented characters?
Yes. Case mapping is Unicode-aware, so ß, İ, dž and Greek final sigma convert according to the Unicode rules rather than the ASCII ones.
What is the difference between camelCase and PascalCase?
Only the first letter. camelCase starts lowercase and is the JavaScript convention for variables; PascalCase starts uppercase and is used for classes and components.
Can I convert only part of my text?
Not selectively — each button converts everything in the box. Paste the section you want to change on its own, convert it, then paste it back into your document.
Do I need to install anything?
No. It is a web page: open it, paste, click a case. There is no sign-up, no extension and no download, and the conversion happens on your device rather than on a server.
Is Case Converter really free, with no limits?
Yes. There is no account, no daily cap, no file-size tier and no watermark, because there is no server cost to recover. The site is funded by clearly disclosed partner recommendations on the Partners page, never by metering the tools.
Are my files or text uploaded when I use Case Converter?
No. Everything is processed by JavaScript running in your browser, on your device. You can verify it: open your browser's developer tools, switch to the Network tab, and use the tool. You will see no request carrying your data — because there is nowhere for it to go.
