Frequently asked questions
Which formats are supported?+–
Eight formats: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, and kebab-case. Useful for writing and for naming variables in code.
Can camelCase and PascalCase work on regular text?+–
Yes, though both work best on short phrases without punctuation. Both strip spaces between words, matching how programming variable names get built.
Does Sentence case fix random capitals mid-sentence?+–
Yes. Sentence case lowercases everything first, then capitalizes the first letter of each sentence and the letter after a period, question mark, or exclamation point.
Is my text stored on a server?+–
No. Every conversion runs in your browser without touching any server.
