Frequently asked questions
What is the difference between Capitalized Case and Title Case?
Capitalized Case makes the first letter of every word uppercase. Title Case follows headline style and keeps small words such as a, an, the, of and in lowercase unless they start the title.
Can I convert text to camelCase or snake_case for coding?
Yes. camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and dot.case are all included. Each line is converted separately, so you can convert a whole list of variable names at once.
Can I undo a conversion?
Yes. Click Undo to step back through your previous conversions, so you can try different cases without losing your original text.
Is my text sent to a server?
No. All conversion happens in your browser. Your text stays on your device.
Does it work with other languages?
Case conversion works for any language that has uppercase and lowercase letters, including accented Latin, Greek and Cyrillic text.
