A little guidance

Change letter case in one click

Choose uppercase for labels, lowercase for a consistent starting point, or simple title case for headings. Uppercase and lowercase use your browser’s Unicode case conversion, so many non-English letters are supported too.

Simple title case capitalizes ASCII words after lowercasing the text. It does not follow a publication style guide or preserve acronyms and names. Review results such as NASA and iPhone before publishing.

  1. Paste your text into the editor, or try the sample.
  2. Choose your settings, then use the primary action button.
  3. Copy or download the result. Use Undo to restore the last change.
Good to know

Simple by design.

Is my text stored anywhere?

No. The tools process text in this browser tab. There is no text upload, browser storage, or account history. Refreshing or leaving the page clears the editor.

Does this work on my phone?

Yes. Use a current browser on a phone, tablet, or computer. Copy may require browser permission; downloading is an alternative.
