Case Converter

Convert text between UPPERCASE, lowercase, Title Case, and Sentence case.

Paste or type text and convert it to any capitalization style with one click. Includes copy and clear buttons.

Case errors are surprisingly common — text accidentally typed in all caps, titles pasted in lowercase, or inconsistent capitalization across a document. The case converter fixes any of these in one click without having to retype anything.

Four conversion modes are supported: UPPERCASE converts every character to capitals; lowercase converts all to small letters; Title Case capitalizes the first letter of every word; Sentence case capitalizes only the first word, treating your text as a flowing sentence.

All processing runs entirely in your browser — your text is never sent to any server. Works on text of any length, from a single word to a multi-thousand word document.

  2. Step 2: Click one of the case buttons: UPPERCASE, lowercase, Title Case, or Sentence case. The conversion is applied instantly.
  3. Step 3: Click "Copy" to copy the result to your clipboard.
