Questions about case converter
Is my text sent to a server?
No. The conversion runs in your browser, so your text stays on your device.
What is the difference between Sentence case and Title Case?
Sentence case capitalizes only the first letter of each sentence. Title Case capitalizes the main words and keeps short words such as "of" and "the" small.
Is there a limit on the amount of text?
The limit depends on your device, not on the site.
Choosing the right mode
Sentence case suits normal writing, such as an email, a caption or a paragraph that was typed in capitals by mistake. Title Case suits headings, where the main words start with a capital and short words such as of and the stay small unless they come first. Capitalized Case makes every word start with a capital, which fits names, product lists and labels. UPPER CASE is for emphasis, acronyms or form fields that require capitals, and lower case is handy for tags, usernames and web addresses.
The two playful modes, alternating and inverse case, are for fun and for testing, not for real documents.
Check names and acronyms afterwards
Sentence case and Capitalized Case make the rest of each word small, so acronyms and brand names can lose their capitals. NASA may become Nasa, and a name like iPhone may change. Read the result once and fix those words by hand.
Style guides differ on which words stay small in a title, so if you are following a specific guide for a publication or an essay, treat the Title Case result as a good first pass and adjust it.
