Frequently asked questions
How does Title Case handle small words?
Short words like “a”, “and”, “of” and “the” stay lowercase unless they start the line, following common headline style.
Can I convert many variable names at once?
Yes. For camelCase, snake_case and the other code cases, each line is converted separately, so you can paste a list.
Is Case Converter free?
Yes. Case Converter is free to use with no sign-up and no watermark.
Are my files uploaded to your server?
No. All processing happens locally in your browser using JavaScript and WebAssembly. Your files never leave your device, which also makes it fast and private.
Does it work on my phone?
Yes. It works in any modern browser on Windows, Mac, Linux, Android and iPhone. Very large files may be slow on older phones.
