Frequently Asked Questions

Q 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.

Examples:

  • Title Case: "The Quick Brown Fox Jumps Over the Lazy Dog"
  • Sentence case: "The quick brown fox jumps over the lazy dog"

Q 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, ensuring your formatting stays intact while only changing the letter cases.

Q 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 that have different capitalization conventions.

For non-English text, UPPERCASE, lowercase, and Sentence case will work perfectly, while Title Case should be used with caution.

Q What are the common use cases for each text case?

UPPERCASE:

Used for emphasis, headings, acronyms, and attention-grabbing text like warnings or announcements.

lowercase:

Used for casual writing, email addresses, URLs, modern design aesthetics, and technical contexts.

Title Case:

Used for book titles, article headlines, proper nouns, formal headings, and professional documents.

Sentence case:

Used for regular text, descriptions, natural reading content, and user interface elements.

Q 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. For optimal speed, we recommend converting texts in smaller chunks if you're working with extremely large documents.
