How to use

  1. Type or paste text.
  2. Choose a case style.
  3. Copy the result.

Examples

“the quick brown fox” becomes “The Quick Brown Fox” (Title Case), “theQuickBrownFox” (camelCase), “the_quick_brown_fox” (snake_case) and “the-quick-brown-fox” (kebab-case).

Title Case vs Capitalized Words

Title Case follows headline style: short words such as “and”, “of” and “the” stay lowercase unless they come first or last. Capitalized Words simply capitalises the first letter of every word.

Good to know

  • Sentence case can't know which words are names, so check proper nouns afterwards.

Frequently asked questions

What is camelCase used for?

Naming variables and functions in languages such as JavaScript and Java. snake_case is common in Python and databases; kebab-case in URLs and CSS.

Does it work with Urdu?

Urdu has no upper and lower case, so those options leave Urdu text unchanged.

Does it keep line breaks?

Yes, for all styles except the programmer formats, which join words into one identifier.
