Text Case Converter
Convert text to UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, and more — all at once. Free, instant, entirely in your browser.
Runs entirely in your browser. Nothing is uploaded.
What this tool does
Converts text into every common case style at once — UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, and an alternating-case novelty — so you can grab whichever one you need without picking from a dropdown first.
How to use it
- Type or paste text into the input.
- Every case style updates automatically below it.
- Copy whichever one you need with its own Copy button.
When each style is actually used
camelCase and PascalCase are the conventional styles for variable and class names in most programming languages — JavaScript, Java, and C# among them. snake_case is the convention in Python and Ruby, and shows up constantly in database column names and environment variables. kebab-case is standard in URLs, CSS class names, and HTML attributes, since it avoids characters that have special meaning elsewhere. Title Case and Sentence case are for actual prose — headings and body text, respectively.
Questions
Is this Case Converter free?
Yes, completely, with no signup and no limit on how much you convert.
Is my text uploaded anywhere?
No. Every conversion happens locally in your browser — nothing you type is sent anywhere.
How does it split words for camelCase, snake_case, and so on?
It recognizes spaces, underscores, and hyphens as word breaks, and also splits before a capital letter that follows a lowercase one — so plain sentences, already-hyphenated text, and existing camelCase or snake_case input all convert sensibly rather than only working on simple space-separated words.
What's the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word — the style used for headings. Sentence case only capitalizes the first letter of each sentence, the way normal prose is written.
