How to Use Title Case Converter

Use the Title Case Converter to convert English titles to title case with small-word rules, acronym preservation, and hyphenated-word handling.

1. Prepare the input - Paste an English headline, article title, subject line, book chapter, or UI label into the text field.
2. Choose the rule - Leave acronyms such as API, HTML, USA, or SQL in uppercase. The converter detects all-uppercase tokens and keeps them unchanged.
3. Check the result - Use the preserve-line-breaks option when you are formatting a list of titles. Each line is treated as its own title, so the first and last word rule is applied separately per line.
4. Use the output - Review hyphenated compounds after conversion. The converter capitalizes important parts of compounds while keeping small words such as of or the lowercase when they are internal parts.

Formula & Theory - Title Case Converter

The Title Case Converter uses these rules:

first word and last word = capitalize
major words = capitalize first letter
small words in the middle = lowercase
acronyms matching all-uppercase tokens = preserve
hyphenated words = apply the same rule to each segment

Title case is not the same as capitalizing every word. Style guides usually lowercase short articles, coordinating conjunctions, and common prepositions when they appear in the middle of a title. This is why “the state of the web” becomes “The State of the Web” rather than “The State Of The Web”.

The converter tokenizes text into words while keeping surrounding punctuation. It applies position-aware rules to the first and last token, checks the small-word list for middle tokens, preserves acronyms, and then handles hyphenated compounds segment by segment. This gives a practical editorial result without requiring a backend grammar service.
