Title Case
The Quick Brown Fox Jumps Over the Lazy Dog
Capitalises the first letter of major words and skips minor words like "and", "the", "of", and "in". Used for article headlines, blog post titles, book titles, and product names.
UPPER CASE
THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG.
Converts every letter to uppercase. Ideal for acronyms, banners, strong emphasis, warning labels, and any text that needs to grab immediate attention.
lower case
the quick brown fox jumps over the lazy dog.
Converts every letter to lowercase. Useful for normalising data, cleaning up text pasted from PDFs or design tools, and preparing content for further processing.
Capitalized Case
The Quick Brown Fox Jumps Over The Lazy Dog.
Capitalises the very first letter of every word without exception — including minor words like "and", "the", and "of". Often used for display names, certificate text, and formal headings.
aLtErNaTiNg cAsE
tHe QuIcK bRoWn FoX jUmPs OvEr ThE lAzY dOg.
Alternates between lowercase and uppercase on every letter, starting with lowercase. Popular for internet memes, ironic humour, and playful or sarcastic social media posts.
InVeRsE CaSe
tHE QUICK BROWN fOX JUMPS OVER tHE LAZY dOG.
Flips the existing case of every character — uppercase letters become lowercase and lowercase letters become uppercase. Handy for reversing text that was accidentally typed with Caps Lock on.
