Frequently asked questions
What is the difference between Title Case and Capitalize Each Word?▾
Capitalize Each Word uppercases the first letter of every word. Title Case follows headline style: small words like a, an, the, and, of, in and to stay lowercase unless they are the first or last word.
How do I change all caps text to normal text?▾
Paste the text and click Sentence case. It lowercases everything, then capitalizes the first letter of each sentence and the word "I".
What are camelCase, snake_case and kebab-case?▾
They are naming styles used in programming: camelCase (myVariableName), PascalCase (MyVariableName), snake_case (my_variable_name), CONSTANT_CASE (MY_VARIABLE_NAME) and kebab-case (my-variable-name), common in URLs and CSS.
Does it work with accented letters and other languages?▾
Yes. Conversion is Unicode-aware, so letters like é, ü, ç, ş and Cyrillic or Greek text are handled correctly.
Is my text uploaded anywhere?▾
No. Everything happens in your browser; the text never leaves your device.
