How to use the text case converter
Paste or type text, choose a case, and select Convert text. Copy the result with the copy button. Uppercase and lowercase preserve punctuation, spaces, and line breaks.
Title, sentence, camel, Pascal, snake, and kebab modes rebuild the input from extracted Unicode words. That means punctuation and original layout are intentionally removed in those modes.
Conversion rules
Words keep their accents and other combining marks. camelCase, PascalCase, snake_case, and kebab-case additionally drop apostrophes, so user's name becomes usersName rather than an identifier no language accepts. Title case keeps them, so It's stays correct.
Title case capitalizes every extracted word rather than following a specific editorial style. Sentence case capitalizes only the first extracted word and does not detect separate sentences. camelCase and PascalCase remove separators. snake_case and kebab-case use underscores and hyphens.
Privacy and limitations
Processing happens in the current browser page. Avoid pasting secrets into any website if your device, browser extensions, clipboard manager, or screen may be monitored.
Automatic casing cannot reliably infer acronyms, brand styling, personal names, or editorial exceptions: NASA becomes Nasa in title case and nasa in snake_case, because every word has its first letter capitalized and the rest lowered. Review important text after conversion.
Uppercase and lowercase use your browser’s language settings, so a few letters can differ between devices. The clearest case is Turkish, where i capitalizes to İ rather than I. Character counts are counted the same way everywhere.
Frequently asked questions
Does this tool upload my text?
No. Conversion runs in your browser. The text you enter is never sent to a server.
Which modes preserve punctuation and line breaks?
Uppercase and lowercase preserve the original layout and punctuation. The other modes extract words and rebuild the text using spaces or the selected separator.
Is title case based on a publishing style guide?
No. It capitalizes the first character of every extracted word and does not apply special rules for articles, conjunctions, acronyms, or names.
Does it support accented and non-English letters?
Word extraction recognizes Unicode letters and numbers. The uppercase and lowercase modes use your browser's language settings, so language-specific casing can vary. Title and sentence case capitalize the first letter without applying those rules.
