Frequently asked questions
Which cases can I convert to?
You can switch text to UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case and kebab-case. Each option updates the output the moment you pick it.
What is the difference between Title and Sentence case?
Title Case capitalises the first letter of every significant word, which suits headings. Sentence case capitalises only the first word and proper nouns, matching normal prose.
How do camelCase and snake_case work?
These programmer styles split your text into words and rejoin them: camelCase removes spaces and capitalises later words, while snake_case and kebab-case join words with underscores or hyphens.
Is my text processed privately?
Yes. All conversion happens locally in your browser with JavaScript. Nothing is uploaded or stored, so you can safely reformat sensitive or unpublished text.
Does it preserve line breaks?
Yes. Simple cases like upper and lower keep your original layout, while the programmer cases collapse whitespace by design so the result is a single valid identifier.
