Questions, answered

What is title case?

Title case capitalizes the first letter of the main words in a heading. Short words such as "a", "and", "of" and "the" stay lowercase unless they start or end the title, following common style guides.

What is sentence case?

Sentence case capitalizes only the first letter of each sentence, like normal writing. It is often used for headings on modern websites and apps.

What are camelCase and snake_case?

They are naming styles used in programming. camelCase joins words and capitalizes each word after the first (myVariableName). snake_case joins words with underscores in lowercase (my_variable_name).

Is my text uploaded anywhere?

No. All conversions happen in your browser, so your text never leaves your device.
