Every case, explained

| UPPERCASE | HELLO WORLD | Emphasis, headings, acronyms |
| lowercase | hello world | Casual text, tags |
| Title Case | Hello World | Titles, headlines |
| Sentence case | Hello world | Body text, modern UI |
| camelCase | helloWorld | Code variables |
| slug-case | hello-world | URLs, file names |
Why a case converter saves time
Retyping a heading just to change its capitalization is tedious and error-prone, and fixing an accidental Caps Lock paragraph by hand is worse. A case converter does it instantly while keeping your words and order intact — paste once, then try each style to see which fits before you copy the result back.
It's equally useful for developers turning a label into a URL slug or a variable name, and for writers matching a publication's house style. Everything runs locally, so even long documents convert instantly and privately.
Frequently asked questions
- What is Title Case?
- Title Case capitalizes the first letter of every major word. It's used for book titles, headlines, and article titles. Note that strict style guides keep small words like 'and', 'of', and 'the' lowercase unless they start the title.
- What is slug-case?
- Slug-case (or kebab-case) converts text to lowercase and replaces spaces and special characters with hyphens, e.g. 'My Blog Post' becomes 'my-blog-post'. It's the standard format for clean, URL-friendly web addresses.
- Is there a limit on text length?
- There's no strict limit — it depends on your browser's memory. You can paste long documents and convert them all at once.
- What is the difference between Sentence case and Title Case?
- Sentence case capitalizes only the first letter of the sentence (and proper nouns), like normal prose. Title Case capitalizes the first letter of each word. Sentence case is increasingly preferred for headings in modern style guides.
- What are camelCase and snake_case used for?
- camelCase ('myVariableName') and snake_case ('my_variable_name') are naming conventions used in programming for variables and functions. Converting between them is handy when moving code between languages with different conventions.
- Does converting case lose any of my text?
- No. Only the capitalization (and, for slug/camel/snake case, the spacing) changes. Your words and their order stay intact, and you can switch between cases without retyping.
