This free case converter does it instantly: UPPERCASE for headings, lowercase for URLs and hashtags, Title Case for article headlines, Sentence case for normal writing, plus aLtErNaTiNg and Reverse Text for fun effects.
Everything runs locally in your browser, so your text stays private. The small counter under the box keeps track of words and characters as you edit.
FAQs
Is the case converter free?
Yes — free forever, no sign-up. All conversion happens instantly in your browser.
What is the difference between Title Case and Sentence case?
Title Case capitalises the first letter of every word, while Sentence case capitalises only the first letter of each sentence.
Will the tool keep my text private?
Yes. The conversion runs entirely in your browser, so your text is never sent anywhere.
Does it handle accented or non-English letters?
Yes — the conversion uses standard Unicode case rules, so accented characters convert correctly too.
