What each case style does (with quick examples)

• lower case
  Converts all letters to lowercase.
  “Hello World!” → “hello world!”

• UPPER CASE
  Makes every letter uppercase.
  “Hello World!” → “HELLO WORLD!”

• Sentence case
  Lowercases the text, then capitalizes the first letter of each sentence after periods, question marks, or exclamation points.
  “THIS IS AMAZING. RIGHT?” → “This is amazing. Right?”

• Capitalized Case (a.k.a. initial caps)
  Capitalizes the first letter of every word; useful for names or headings where you want consistent first-letter caps.
  “best pc optimization tools” → “Best Pc Optimization Tools”

• Title Case
  Capitalizes major words while keeping short conjunctions and prepositions (like and, of, in, to) lowercase—unless they start or end the title. Hyphenated words are handled smartly.
  “speed up your windows pc in 10 minutes” → “Speed Up Your Windows PC in 10 Minutes”
  “state-of-the-art guide” → “State-of-the-Art Guide”

• aLtErNaTiNg cAsE

  “optimize performance” → “oPtImIzE pErFoRmAnCe”

• InVeRsE CaSe
  Flips each letter’s case, upper → lower and lower → upper.
  “Quick Fix” → “qUICK fIX”
