Case converter FAQ
What is the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of each major word (nouns, verbs, adjectives, etc.) while leaving minor words (articles, prepositions, conjunctions) lowercase, following standard title formatting rules. Sentence case only capitalizes the first letter of each sentence and proper nouns, treating the text like regular sentences.
Does the case converter work with special characters and numbers?
Yes, our case converter handles special characters, numbers, punctuation, and symbols correctly. Only alphabetical characters are affected by case conversion - numbers, symbols, and punctuation marks remain unchanged. The tool also preserves spacing and line breaks in your original text.
Can I convert text in languages other than English?
Yes, the case converter works with most languages that have uppercase and lowercase letters, including Spanish, French, German, Italian, Portuguese, and many others. However, Title Case formatting follows English grammar rules, so it may not be linguistically correct for other languages.
What are the common use cases for each text case?
UPPERCASE is used for emphasis, headings, acronyms, and attention-grabbing text. lowercase is used for casual writing, email addresses, URLs, and modern design aesthetics. Title Case is used for book titles, article headlines, proper nouns, and formal headings. Sentence case is used for regular text, descriptions, and natural reading content.
Is there a limit to how much text I can convert?
No, there's no strict limit on the amount of text you can convert. Our tool can handle anything from single words to large documents. However, for very large texts (over 50,000 characters), you may experience slower processing times depending on your device's performance.
