How to Change Text Case Online (UPPER, lower, Title)
We've all done it — typed a whole sentence with Caps Lock on, or pasted a heading that's in the wrong case. Retyping is a waste of time. A case converter transforms your text between different letter cases instantly, so you can fix mistakes and format headings in one click.
The main text cases explained
- UPPERCASE — every letter capital. Good for short emphasis, but hard to read in long blocks.
- lowercase — every letter small. Useful for a relaxed style or fixing accidental caps.
- Title Case — The First Letter Of Each Word Is Capital. Perfect for headings and titles.
- Sentence case — Only the first letter of each sentence is capital, like normal writing.
Step-by-step: change your text case
- Open the Case Converter.
- Type or paste your text into the box.
- Click the case you want — UPPERCASE, lowercase, Title Case or Sentence case.
- Click Copy to grab the result.
When to use each case
Use Sentence case for most writing — it's the easiest to read. Reserve UPPERCASE for very short labels or warnings. Title Case makes headings look polished, and lowercase can give a modern, informal feel to social media captions and brand names.
Frequently Asked Questions
Will it change my original text?
No. The tool only changes what's displayed in the box; your source document elsewhere stays untouched until you paste the new version.
Does it work with other languages?
Yes, for most Latin-based alphabets. Accented characters are handled correctly.
Is there a character limit?
No practical limit — you can convert anything from a title to a full article.
Can it fix a whole paragraph typed in caps?
Yes. Paste it in and choose Sentence case to instantly restore normal capitalisation.
Is my text private?
Completely. Conversion happens in your browser and nothing is stored or uploaded.
