Text Case Converter FAQs
Is this text case converter free?
Yes, it is completely free with unlimited conversions. No accounts, no credits and no hidden fees.
What case styles are supported?
UPPERCASE, lowercase, Title Case (first letter of each word capitalized), Sentence case (first letter of each sentence), tOGGLE cASE (every letter flips) and aLtErNaTiNg case.
How does Title Case differ from Sentence case?
Title Case capitalizes the first letter of every word, which suits headings. Sentence case only capitalizes the first letter of the text and each sentence, like normal prose.
Does the converter handle long documents?
Yes. Conversion is instant even for very long texts because everything is processed locally in your browser, not on a server.
Do my texts leave my browser?
No. The entire conversion runs on your device — nothing you type is uploaded, stored or logged anywhere.
