About this tool

Retyping a paragraph because caps lock was on is wasted effort. Paste the text, click a case, and copy the result. Title Case capitalizes each word's first letter; Sentence case capitalizes the first letter after each sentence-ending punctuation mark and lowercases the rest. Conversions are instant and reversible — your original stays in the input box.

Frequently asked questions

Does Title Case handle small words like "and" or "the"?
This converter capitalizes every word, which is the safest general rule. Style guides differ on lowercasing short words — adjust those few by hand if your style guide requires it.
Will Sentence case fix names like "london"?
No — it only knows sentence boundaries, not proper nouns. Correct names afterwards; the Find and Replace tool can help for repeated ones.
Is there a length limit?
No practical one — conversion is instant even for very long documents, because it all happens in your browser.
