Frequently asked questions
How does Title Case treat small words?
Small words such as a, an, the, of, and, or and to stay lowercase, except when they are the first or last word of a line.
Which cases can I use for code?
camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE. Words are split on spaces, punctuation and existing case changes, so fooBar and foo-bar both become foo_bar.
Are my files uploaded anywhere?
No. Case Converter runs entirely in your browser. Your files are processed on your device and are never sent to a server.
Is there a file size limit?
No fixed limit. The only limit is your device's memory. Very large files work best in a desktop browser.
Is Case Converter really free?
Yes. There's no account and no watermark. A short optional ad, or a 20-second wait, unlocks each download. That's how we keep it free.
Does it work offline?
Once the page has loaded, processing happens locally, so it keeps working even if your connection drops.
