Case converter is a free tool that runs entirely in your browser, with no data ever sent to a server. Switch text to UPPERCASE, lowercase, or Title Case.

Five ways to change case

"Each Word" capitalizes the start of every word, useful for a title. "Each sentence" only capitalizes the start of each sentence, as in normal prose. Alternating case has no practical use : it's mostly there to imitate a mocking tone online.

What this tool does not do

This tool only applies the transformation described above, with no spelling correction and no understanding of the text's meaning. A text of tens of thousands of lines is processed instantly ; beyond that, the only limit is your device's memory.

Frequently asked questions

Are accented letters preserved?

No : the text you type or paste is processed entirely in your browser, on your device. It is never transmitted to a server.

Do I need to create an account or install anything?
