Frequently asked questions
Is my text sent anywhere?
No. Conversion runs entirely in your browser with JavaScript — nothing is uploaded or stored.
What is the difference between Title and Sentence case?
Title Case capitalises The First Letter Of Every Word; Sentence case only the first letter of each sentence.
What are camelCase and snake_case?
camelCase joins words with each subsequent one capitalised (myVariableName); snake_case links them with underscores (my_variable_name). Handy for code.
Does it work with Cyrillic?
Yes for UPPER/lower/Title/Sentence. The “programmer” cases strip spaces and are intended for Latin text.
