Frequently asked questions
- Is the Case Converter free to use?
- Yes, it is completely free with no sign-up, no usage limits, and no watermarks. You can convert as much text as you want, as often as you like.
- Is my text uploaded or stored anywhere?
- No. All conversion happens locally in your browser using JavaScript. Your text never leaves your device, is never sent to a server, and is not saved anywhere. Once the page loads it even works offline.
- What case styles can I convert to?
- Seven styles: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case, and kebab-case. Just choose one from the dropdown and the result updates instantly.
- What is the difference between Title Case and Sentence case?
- Title Case capitalizes the first letter of each major word (keeping small words like 'and' or 'the' lowercase), which is common for headlines. Sentence case only capitalizes the first letter of each sentence, like normal prose.
- How do camelCase, snake_case, and kebab-case work?
- These programmer-friendly formats split your text into words on spaces, punctuation, and capital-letter boundaries, then rejoin them. camelCase joins words with no spaces and capitalizes each after the first (myVariableName), snake_case joins with underscores (my_variable_name), and kebab-case joins with hyphens (my-variable-name).
- Can I copy the converted text easily?
- Yes. Click the Copy result button and the converted text is placed on your clipboard, ready to paste anywhere. The tool also shows live character, word, and line counts as you type.
