Case Converter
A text case converter to convert to uppercase, lowercase, title, sentence or toggle case without uploading the text.
A paragraph typed with Caps Lock does not need to be rewritten. tOGGLE cASE swaps each uppercase and lowercase letter, while the UPPERCASE and lowercase buttons make every cased character uniform. Once a mode has been chosen, edits in the input are converted again automatically.
A title case converter follows word boundaries
Title Case lowercases the text first and then capitalizes the beginning of each word. Apostrophes inside contractions stay inside the word, so don't becomes Don't rather than Don'T. This mechanical rule does not apply a publisher's style guide or restore proper nouns that were entered incorrectly.
Case changes can affect data
Before you convert to uppercase or lowercase, consider where the result will be used. Accented characters are preserved, but some letters can expand under Unicode rules; German ß, for example, becomes SS. Case-sensitive passwords, source code and hash inputs may produce a different value after conversion.
Processing stays in the browser. The input is not uploaded. Copy the result or use Move to Input when another pass is needed.
Frequently Asked Questions About the Case Converter
Title Case capitalizes the start of each detected word. Sentence case lowercases the text and then capitalizes only the first cased letter at the beginning, after sentence-ending punctuation, or after a new line.
No. The conversion runs in your browser, and the input is not sent to the server. You can copy the output or move it back to the input for another pass.
