Case Converter
Convert text to uppercase, lowercase, title, camelCase, snake_case, and more, instantly.
Best for English/number text. Grab each result with its copy button.
What formats can I get?
Paste text and it's converted at once into seven forms: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case, and kebab-case. A copy button next to each result grabs it instantly.
When to use it
- Development: quickly standardize variable and function names to camelCase or snake_case.
- Docs and titles: tidy English titles into Title Case.
- Data cleanup: normalize a list with mixed casing into one form.
Things to note
- camelCase and snake_case conversions treat spaces, hyphens, and underscores as word separators.
- Proper nouns and acronyms (e.g., iOS, NASA) may need manual touch-up after conversion.
- Best suited to English/number text; some scripts have no letter case.
The text you enter is converted only in your browser and is never sent to or stored on a server.

What's the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word (e.g., The Quick Brown Fox), while Sentence case capitalizes only the first letter of the sentence (e.g., The quick brown fox).
When do I use camelCase or snake_case?
Mostly in programming. camelCase (myVariableName) is common for JavaScript variables, and snake_case (my_variable_name) for Python and database columns.
Is my text stored?
No. Conversion happens entirely in your browser and the text you enter is never sent to or stored on a server.
