Use UPPER CASE for capital letters, lower case to decapitalize text, Sentence case for regular sentences, Title Case for headings, or one of the additional formats for creative and technical text.
Turn ALL CAPS into lowercase instantly. Select lower case to decapitalize text, convert upper to lower case, fix accidental Caps Lock, or standardize uppercase text without retyping it.
Example: "THIS TEXT IS IN CAPITAL LETTERS" becomes "this text is in capital letters".
Use the uppercase converter to convert lowercase text to uppercase capital letters for headings, labels, warnings, or consistent formatting.
Example: "this text is in lowercase letters" becomes "THIS TEXT IS IN LOWERCASE LETTERS".
Sentence case capitalizes the first letter of the text and the first letter after supported sentence-ending punctuation while converting other letters to lowercase.
Title Case capitalizes the first and last word and most other words while leaving common short articles, conjunctions, and prepositions lowercase.
Examples: Sentence case: "This is an example." Title Case: "This Is an Example of Title Case."
Use the camelCase converter to turn words and phrases into common technical naming formats for variables, class names, database fields, configuration keys, and URL slugs.
camelCase starts with a lowercase word; PascalCase capitalizes the first word; snake_case uses underscores; kebab-case uses hyphens. Hyphens are commonly used to separate words in URL slugs.
Create text that alternates between lowercase and uppercase letters for memes, usernames, and playful social posts.
The inverse-case option works as a case inverter: it swaps every uppercase letter to lowercase and every lowercase letter to uppercase. This can fix text entered with reverse Caps Lock.
