Convert text between cases instantly.
How This Works
All conversions happen instantly in your browser — nothing is sent to a server. Title Case capitalizes the first letter of each word; Sentence case capitalizes only the first letter of each sentence.
Guide: understanding your result
Key points
- Sentence case capitalizes only the first word and proper nouns; title case capitalizes the major words of a heading.
- Style guides disagree on title case details: AP capitalizes words of four or more letters, Chicago lowercases articles, coordinating conjunctions and prepositions regardless of length.
- Programmers use camelCase, PascalCase, snake_case and kebab-case for identifiers, file names and URLs.
Case styles at a glance
| Style | Example | Typical use |
|---|---|---|
| Sentence case | How to plan a monthly budget | Body headings, UI labels |
| Title case | How to Plan a Monthly Budget | Article and book titles |
| UPPERCASE | HOW TO PLAN A MONTHLY BUDGET | Short labels, acronyms |
| camelCase | monthlyBudget | JavaScript variables |
| snake_case | monthly_budget | Python, databases |
| kebab-case | monthly-budget | URLs, CSS classes |
Common mistakes to avoid
- Writing long passages in all caps — it reduces readability and reads as shouting.
- Letting automatic title case lowercase brand names or acronyms (iPhone, NASA); check these by hand.
Frequently asked questions
Is the text I paste stored?
No. The conversion runs in your browser and the text is not sent to our server.
Which title case should I use?
Follow the style guide your publication or organization uses; consistency matters more than the choice itself.
