Why convert text case
Retyping text in a different case by hand is slow and error-prone, especially for long passages, headlines, or code identifiers that follow strict naming conventions.
This tool applies the conversion instantly in your browser as you type, so you can try several case styles on the same text without retyping anything.
Choosing a case style
| Style | En uygun olduğu durumlar | Neden göz atmaya değer? |
|---|---|---|
| Title Case Common | Headlines, titles | Capitalizes each major word for a polished, readable heading. |
| camelCase / PascalCase | Variable and class names in code | Matches naming conventions used in JavaScript, Java, and similar languages. |
| snake_case / kebab-case | File names, URLs, database columns | Widely used in Python, CSS, and URL slugs instead of camelCase. |
Case Converter without uploading anything
The text you type is read directly by JavaScript running in your browser tab, converted on the spot, and shown back to you — it's never transmitted to a server, logged, or stored.
Because there's no upload involved, there's no practical length limit beyond what your browser's memory can comfortably handle.
Your text never leaves your device. Case conversion is pure client-side JavaScript, with nothing logged or stored.

camelCase vs. snake_case — which should you use?
| Style | En uygun olduğu durumlar | Ödünleşme |
|---|---|---|
| camelCase / PascalCase JS, Java, C# | Variables, functions, class names | Standard in most C-family and JS-family languages. |
| snake_case Python, SQL | Variables, file names, database columns | Standard in Python, Ruby, and most SQL conventions. |
| kebab-case | URLs, CSS class names, file names | Common on the web since hyphens are safe in URLs; not valid as a variable name in most languages. |
When in doubt, match whatever convention the rest of your project already uses — consistency matters more than which style you pick.
