About this tool

Typed a whole paragraph with Caps Lock on? Need a headline in proper Title Case, or a legal doc in sentence case? This case converter fixes text casing with one click — no retyping.

Seven conversions are included: UPPERCASE and lowercase for the basics; Title Case, which capitalizes principal words while keeping short words like "of" and "the" lowercase (the convention used by headlines and book titles); Sentence case, which capitalizes only the first letter after each full stop; Capitalize Each Word for names and lists; plus aLtErNaTiNg and iNVERSE case for social posts.

Your line breaks and spacing are preserved exactly, the character counter tracks length as you work, and everything runs in your browser — the text is never uploaded anywhere.

How to use

  1. Paste or type your text.
  2. Click the case style you need — the text converts in place.
  3. Click Copy result and paste it wherever it belongs.
