Paste text and convert it instantly between UPPERCASE, lowercase, Title Case and Sentence case — entirely in your browser.
What this converter does
Paste any text and switch it between the four cases people actually need: UPPERCASE for emphasis and headings, lowercase to undo an accidental caps-lock paragraph, Title Case for headlines, and Sentence case to normalise text that arrived shouting. The conversion happens live in your browser — nothing you paste is transmitted anywhere, which matters when the text is unpublished work.
How to use it
- Paste or type the text.
- Pick the case.
- Copy the converted result from the output row.
The four cases
A worked example
“the quick brown fox jumps over the lazy dog” becomes The Quick Brown Fox Jumps Over The Lazy Dog in Title Case — every word capitalised. Publishing style guides differ on the small words: AP capitalises everything of four letters and up, while many house styles lower “the/of/and” mid-title. This converter capitalises every word and leaves the style-guide exceptions to your judgment, which is the only honest way to do it automatically.
