Why Use This Tool?
The caps-lock landslide happens to everyone: a paragraph typed with caps-lock on, a headline that needs title case, a form that demands lowercase. This case converter fixes all five directions live — the output updates as you type, so there isn't even a button to press.
Word capitalization, sentence detection after periods and question marks, and true character-by-character toggling all run locally, so private text stays on your machine.
How It Works
- Paste or type your text into the input box.
- Click a case style — the converted text appears instantly in the output box.
- Copy the result with one click, or keep switching styles until it looks right.
Frequently Asked Questions
How do I convert text to uppercase or lowercase?
Paste your text, click UPPERCASE or lowercase, and copy the result. The conversion is instant and works on any length of text.
What is sentence case?
Sentence case lowercases everything, then capitalizes the first letter after each period, question mark, or exclamation point — the way normal sentences are written.
What does toggle case do?
It flips every letter to its opposite: 'Hello World' becomes 'hELLO wORLD'. Handy for fixing that caps-lock accident without retyping.
