What this tool does
Case Converter changes the capital letters in your text without retyping it. Fix text that was typed with Caps Lock on, turn a sentence into a headline, or format words for code.
Title Case follows common headline style: small words such as “and”, “of” and “the” stay lowercase unless they start or end the title. Sentence case capitalises the first letter of each sentence and the word “I”.
Who it helps
- Writers and editors formatting headlines and fixing Caps Lock mistakes.
- Students tidying titles for essays and reports.
- Social media managers styling captions and post titles.
- Developers turning phrases into camelCase, snake_case or kebab-case names.

Frequently asked questions
What is the difference between Title Case and Capitalize Each Word?
Title Case keeps short words like “of”, “and” and “the” in lowercase, as in most headlines. Capitalize Each Word makes the first letter of every word a capital.
Will it keep my line breaks?
Yes. Line breaks and paragraphs stay exactly where they were, except in the code styles, which join words into one name.
Why did a name become lowercase?
The tool can’t tell names from ordinary words. After using Sentence case or lowercase, quickly check names, places and acronyms.
Is my text uploaded?
No. The conversion happens in your browser and nothing is saved.
