This tool rewrites pasted text into UPPERCASE, lowercase, Title Case, or Sentence case in one click. It is handy for cleaning up headlines, fixing all-caps copy, or normalizing inconsistent capitalization before publishing.

How this is calculated

Upper and lower apply the standard string case transforms; Title Case capitalizes the first letter of each word and lowercases the rest, while Sentence case lowercases everything then capitalizes the first letter and any letter following a period, exclamation point, or question mark.

How to use

  1. Paste your text into the box.
  2. Pick a case: UPPER, lower, Title, or Sentence.
  3. Copy the converted text.

Examples

  • Title Case: hello world → Hello World
  • Sentence case: hello. world → Hello. World
