What case formats are available?

Common formats include UPPERCASE (all caps), lowercase (all small), Title Case (first letter of each word), Sentence case (first letter of sentence), and camelCase (for programming).

Can I convert code or programming text?

Yes, case converters work with any text including code. However, be careful with code as changing case may break syntax in some programming languages.

Does the converter preserve formatting?

The converter changes capitalization but preserves line breaks and spacing. Special formatting like bold or italic may be lost depending on where you paste the result.

Can I convert multiple paragraphs?

Yes, you can convert entire documents with multiple paragraphs. Each paragraph will be converted according to the selected case format.

Is my text secure?

Yes, all conversion happens entirely in your browser. Your text never leaves your device or is sent to any server.

What is Title Case?

Title Case capitalizes the first letter of each major word. Articles, prepositions, and conjunctions are typically lowercase unless they're the first word.

What is camelCase?

camelCase is a naming convention where the first word is lowercase and subsequent words start with uppercase, with no spaces. Example: firstName, lastName, emailAddress.

Can I convert file names?

Yes, you can convert file names, but remember that some operating systems are case-sensitive. Always test file names after conversion.

Does it work with special characters?

Yes, the converter handles special characters, numbers, and symbols. Only letters are affected by case conversion.

Can I undo the conversion?

The converter doesn't store your original text, so you'll need to paste it again if you want to convert to a different case. Keep a copy of your original text if needed.
