CaseKit is a free online case converter that transforms text between multiple capitalization styles. It supports UPPERCASE, lowercase, sentence case, title case, capitalized case, alternating case, inverse case, toggle case, and programming formats like camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and dot.case.

All text processing happens in your browser using JavaScript, so your text is never uploaded to a server or saved. The tool preserves line breaks, spacing, numbers, punctuation and emoji while converting only the letters. It includes language-aware rules for English, Spanish, Portuguese and German with correct handling of accented letters, and can keep acronyms and brand names capitalized across different case styles.

The converter offers multiple title case style guides including AP, APA, Chicago and MLA formats. It provides live character, word and line counts, works on phones, tablets and desktops, and is fully usable with keyboards and screen readers.

Questions from the bench

Is this case converter free?
Yes. Every feature is free to use, with no account, no limits on normal use and no watermark.
Is my text saved or sent anywhere?
No. The conversion happens entirely in your web browser using JavaScript. Your text is never uploaded to a server, logged or saved — closing the tab removes it.
What's the difference between sentence case and title case?
Sentence case capitalizes only the first word of each sentence and proper nouns. Title case capitalizes most words and keeps short words like "and" or "of" lowercase.
Does it work with accents and other languages?
Yes. Accented and non-English letters are converted correctly, and you can choose English, Spanish, Portuguese or German rules. However, no automatic tool can know which words are names, so you may need to check those by hand.
Will it keep my line breaks and spacing?
Yes. Only letters change. Line breaks, multiple spaces, tabs, numbers, punctuation and emoji stay exactly where they were.
