Five case styles, one click each

UPPERCASE and lowercase are the two most requested conversions — useful for headings, acronyms, or cleaning up text that was typed with Caps Lock stuck on. Title Case capitalises the first letter of every word, ideal for headlines and page titles. Sentence case capitalises only the first letter of each sentence, matching normal prose. Alternating case is a fun formatting style used for emphasis or memes.

Frequently asked questions

Does it work with Uzbek Cyrillic and Latin special letters?+

Yes — all five case modes handle standard Latin and Cyrillic letters correctly, including capitalising the first letter after punctuation.

Can I convert a whole paragraph, not just one line?+

Yes, paste as much text as you like — multi-paragraph documents work exactly the same as a single sentence.
