About Case converter conversion

Everyone has typed a paragraph with caps lock on, received a spreadsheet column of SHOUTING product names, or needed to turn a list of lowercase titles into proper headings. Retyping is tedious and error-prone. The case converter rewrites the whole block in one click with four styles: UPPERCASE, lowercase, Title Case, and Sentence case.

Each style follows simple, predictable rules. Title Case lowercases everything and then capitalizes the first letter of every word, including short words like "of" and "the" — perfect for name lists and product catalogs, though editorial style guides may want a few small words lowered by hand afterward. Sentence case lowercases the text and capitalizes the first letter at the start and after each period, question mark, or exclamation mark. Because of that, proper nouns and acronyms such as "NASA" or "Paris" will need a quick touch-up.

A live counter under the text box reports characters, words, and lines, so you can check limits for meta descriptions, social posts, or form fields while you edit. When you are done, copy the result or download it as a .txt file.

How to do it

  1. Open the Text tool with the button above; the case buttons are highlighted.
  2. Paste or type your text into the box.
  3. Click UPPERCASE, lowercase, Title Case, or Sentence case.
  4. Fix any proper nouns or acronyms the rules lowercased.
  5. Press Copy text, or Download .txt to save the result.

Case converter FAQ

Does Title Case skip small words like 'and' or 'of'?

No. Every word gets a capital first letter. Lower minor words by hand if your style guide requires it.

Why did Sentence case lowercase names?

Sentence case lowercases everything first, then capitalizes sentence starts. Re-capitalize proper nouns afterwards.

Can I undo a change?

Use your browser's undo (Ctrl/Cmd+Z) in the text box, or simply apply another case style.

Is there a length limit?

No fixed limit; very long documents depend only on your device's memory.
