Frequently Asked Questions

What does the Title Case Converter do?
It converts text into title case, sentence case, uppercase, or lowercase using common headline capitalization rules. This helps you format blog titles, headings, emails, and content for publishing.
What is the difference between AP and Chicago title case?
AP style keeps many short words (articles, conjunctions, and prepositions) lowercase, while Chicago style capitalizes more words. Smart case is a practical default when you do not need strict style-guide rules.
Can I keep specific words lowercase or preserve acronyms?
Yes. Add custom exceptions (like product names) and enable acronym preservation so terms like AI, NASA, or HTML stay correctly capitalized.
Does it change punctuation or spacing?
No. It only changes letter casing. Punctuation, quotes, emojis, and spacing remain the same.
Is this Title Case Converter safe to use?
Yes. It runs 100% client-side, so your text stays in your browser and is not uploaded to a server.
