Frequently asked questions
Is my text uploaded?
No. The conversion happens entirely in your browser with JavaScript. Your text is never uploaded, stored or sent to any server.
What is the difference between Title Case and Sentence case?
Title Case capitalises the first letter of every word, which suits headings and titles. Sentence case capitalises only the first letter of each sentence, like normal writing.
When would I use camelCase, snake_case or kebab-case?
These are naming styles used in code and URLs. camelCase joins words with capitals (myVariableName), snake_case uses underscores (my_variable_name), and kebab-case uses hyphens (my-variable-name).
Can I convert a large amount of text?
Yes. There is no practical limit for normal documents because everything runs locally. Very large pastes may feel slower on older devices.
