Frequently asked questions

What case styles are supported?
Common styles include uppercase, lowercase, title case, sentence case, camelCase, PascalCase, snake_case and kebab-case.
Will special characters be affected?
Only letter casing changes. Numbers, punctuation and symbols remain untouched unless the chosen style specifically transforms word boundaries.
Is there a character limit?
There is no hard server-side limit because processing happens in your browser. Very large texts may slow down depending on your device.
