Frequently asked questions

Does it handle acronyms and abbreviations correctly in Title Case?
Title Case capitalizes the first letter of each word but doesn't know which words are meant to stay as acronyms (like NASA or USA). It treats them like any other word, so double-check names and acronyms after converting and fix them by hand if needed.
What's the difference between camelCase and PascalCase here?
camelCase starts with a lowercase letter (firstName), while the PascalCase option capitalizes the first letter too (FirstName). Both strip spaces and join words, which is why they're common for variable and class names in code.
Is my text uploaded anywhere?
No. The conversion happens entirely in your browser with JavaScript, so pasted text (even passwords, code, or drafts) never leaves your device or hits a server.
