Case Styles Explained

lowercase: All letters become small letters. Best for data normalization and some programming uses.

UPPERCASE: All letters become capital letters. Used for headings, legal forms, and emphasis.

Sentence case: First letter of each sentence is capitalized. Natural reading format for body text.

Title Case: Major words are capitalized, minor words (a, an, the, and, etc.) stay lowercase unless starting the title. Standard for book titles and headlines.

Capitalize Every Word: Every single word starts with a capital letter. Sometimes used for names and labels.

tOGGLE cASE: Inverts current case of each letter. Useful for fixing caps lock mistakes.

Frequently asked questions

What is sentence case?

Sentence case capitalizes only the first letter of each sentence and proper nouns, like normal written text. Example: 'This is a sentence. Here is another one.'

What's the difference between title case and capitalize words?

Title case follows English title rules where minor words (a, an, the, and, etc.) stay lowercase unless they start the title. Capitalize words simply capitalizes every word regardless.

What does toggle case do?

Toggle case inverts every character: uppercase becomes lowercase and vice versa. Useful for fixing text typed with caps lock accidentally on.

Is my text saved anywhere?

No. Everything runs in your browser using JavaScript. Your content stays on your device with no server communication.

Does it work with non-English text?

Yes! The tool works with any language that has uppercase and lowercase letters, including Spanish, French, German, and more.
