Case Converter
Paste text, click a case, copy the result. Beyond the basics (UPPERCASE, lowercase, Title Case, Sentence case), it also outputs camelCase, snake_case and kebab-case — the formats developers and writers constantly need for variable names, URLs, filenames and hashtags.
Everything runs locally in your browser, so it is safe for private or sensitive text. There is no length limit — convert a headline or an entire chapter.
How to use
- Paste or type your text into the input box.
- Click the case style you need — the output box updates instantly.
- Use the copy button to grab the converted text.
Frequently asked questions
What is Title Case?
Title Case capitalizes the first letter of each major word ('The Quick Brown Fox'). Minor words like 'a', 'of', 'the' are traditionally lowercase unless they start the title.
What is the difference between camelCase and snake_case?
camelCase removes spaces and capitalizes each word after the first ('myVariableName'). snake_case replaces spaces with underscores and lowercases everything ('my_variable_name'). kebab-case uses hyphens ('my-variable-name').
How do I fix text that's ALL IN CAPS?
Click 'Sentence case' — it lowercases everything except the first letter of each sentence. Or 'Title Case' if it is a heading.
Is my text sent to a server?
No. All conversion happens in your browser with JavaScript. Nothing is uploaded, logged or stored — refresh the page and it is gone.
