About Case Converter
This case converter rewrites your text into a different letter case without you having to retype anything. Paste a sentence, a heading, a variable name, or a whole paragraph, choose the case you want, and the result updates instantly.
It is handy for cleaning up headings, fixing text that arrived in all caps, formatting labels, or turning a few words into a camelCase or snake_case identifier for code.
How to Use
- Choose the case you want from the buttons at the top.
- Type or paste your text into the input box.
- Read the converted text in the output box on the right.
- Click Copy to copy the result to your clipboard.
Frequently Asked Questions
Is this case converter free?
Yes. It is completely free, needs no signup, and has no limit on how much text you convert.
What is the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word, which suits headings. Sentence case capitalizes only the first letter of each sentence, which suits normal prose.
Is my text private?
Yes. All conversion happens locally in your browser, so your text is never uploaded or stored.
