A LITTLE GUIDANCE

How to use this tool

  1. Paste the original text.
  2. Choose upper, lower, title or sentence case, then process.
  3. Compare with the untouched original above and copy the result.

A worked example

hello WORLD → HELLO WORLD in uppercase mode; undo restores the exact input.

What to know

Uses English casing conventions. Title case capitalizes word starts; it is not an editorial style guide and does not preserve acronyms. Sentence case uses punctuation followed by whitespace.

Supported inputs and limits

100,000 input characters.

Where is my data processed?

In your browser. Cloud saving is optional: only the supported inputs, settings or files you explicitly choose are uploaded. Download or save anything you want to keep before closing the page. Read our privacy details.
