Convert any text into a dozen common cases at once — UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case and Train-Case. Every result updates as you type, ready to copy. It all runs in your browser; nothing is uploaded.
How to use
- Type or paste your text into the box.
- Every case is generated instantly below as you type.
- Click copy on the case you need.
How it works
Your text is first split into words. The converter recognizes spaces and symbols as separators, and also detects boundaries inside camelCase and PascalCase (so HTTPRequest becomes http and request). Each case then rejoins those words with its own rule — for example snake_case joins them with underscores, while Title Case capitalizes each word.

Notes

- Case styles like camelCase work best with Latin letters and numbers.
- All processing runs on your device; your text is never uploaded.
FAQ
- What is camelCase?
- camelCase joins words with no spaces and capitalizes each word except the first, like myVariableName. It is common for variables in many programming languages.
- What is snake_case?
- snake_case joins words in lowercase with underscores, like my_variable_name. It is widely used for variables, files and database columns.
- How does Title Case work here?
- Title Case capitalizes the first letter of every word. For strict editorial title rules (leaving small words lowercase), review the result by hand.
- Does it work with non-Latin text?
- Upper and lower case work broadly, but programming cases like camelCase are designed for Latin letters and numbers.
- Is my text sent to a server?
- No. All conversion happens locally in your browser and nothing is uploaded.
