Convert text to any case
This case converter changes the capitalization of your text into every common format at once. Type or paste your text and you get UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE side by side, each with its own copy button. It is built for writers cleaning up headings and for developers renaming variables and keys.
What each case is for
- Title Case capitalizes each word, useful for headlines.
- Sentence case capitalizes only the first letter of each sentence.
- camelCase and PascalCase are common for variables, functions, and class names in code.
- snake_case and kebab-case are used for file names, database columns, and URL slugs.
- CONSTANT_CASE is the convention for constants and environment variables.
Frequently asked questions
How do I convert text to uppercase or lowercase?
Paste your text and copy the UPPERCASE or lowercase row. Both update instantly as you type.
How do I convert a sentence to camelCase or snake_case?
The tool splits your text into words and rebuilds it, so a phrase like "user first name" becomes userFirstName or user_first_name, ready to copy.
Does it work on existing camelCase or snake_case input?
Yes. It detects word boundaries in mixed input, so you can convert between any two cases, not just from plain sentences.
Is my text sent anywhere?
No. All conversion runs in your browser and nothing is uploaded.
