What is a text case converter?
A case converter changes the capitalization style of text without altering the words themselves. Pixvert's case converter supports UPPERCASE, lowercase, Title Case, Sentence case, and the programming-specific styles camelCase, PascalCase, snake_case, and kebab-case — all generated instantly from the same input.
This tool is useful for two very different audiences: writers who need consistent capitalization in headlines or documents, and developers who need to convert a variable or file name between naming conventions, such as turning "user_first_name" into "userFirstName" for JavaScript or "user-first-name" for a URL slug.
Manually retyping text in a different case is slow and error-prone, especially for longer strings or when converting between programming naming conventions where word boundaries need to be tracked precisely. This tool handles all the conversions live as you type.

Frequently Asked Questions
Is my text sent to a server?
No, all case conversion happens locally in your browser using JavaScript. Nothing is transmitted or stored.
What's the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter (userName), while PascalCase starts with an uppercase letter (UserName). Both remove spaces and capitalize each subsequent word.
How does Title Case handle small words like "and" or "the"?
The tool capitalizes the first letter of every word by default. For style guides that lowercase certain small words, you may need to adjust those manually after conversion.
Can I convert code variable names with this tool?
Yes, snake_case, camelCase, PascalCase, and kebab-case are all commonly used in programming, and this tool converts between them directly.
Does the tool handle punctuation and numbers correctly?
Yes, punctuation is preserved for writing case styles (UPPERCASE, lowercase, Title Case, Sentence case), while programming case styles strip spaces and special characters to form valid identifiers.
Is there a text length limit?
No hard limit is enforced, though very large amounts of text may take a moment to process depending on your device.
