Case Converter — a small but mighty text utility that quickly converts text between UPPER CASE, lower case, Title Case, Sentence case, Capitalized Case, alternating case, and toggle case. Great for cleaning up pasted text, preparing headings, or fixing inconsistent capitalization.

How to use

  1. Paste or type your content into the box.
  2. Click any case button to instantly transform the text.
  3. Use Copy To Clipboard to quickly paste the result elsewhere.

Why this is useful

Consistent capitalization matters — for headlines, product listings, form data, or code comments. This tool saves manual editing time and helps keep your content clean and professional.

Tips

  • Use Title Case for blog and article titles.
  • Use Sentence case for normal paragraph text or UI copy.
  • If you paste text with odd punctuation or newlines, use the stats area to check words/sentences before and after.

FAQ

Will punctuation or numbers be changed?
No — only the letters are transformed. Punctuation and numbers remain intact.
