Text case refers to whether letters in a word are written in upper or lower form. Different contexts call for different cases — a heading needs Title Case, a variable name needs camelCase, a shout needs UPPERCASE. Converting by hand is slow and error-prone. This tool does it in one click.
Here's a quick reference for every case this tool supports:
| Case | Example | Common use |
|---|---|---|
| UPPERCASE | HELLO WORLD | Headings, acronyms, emphasis |
| lowercase | hello world | URLs, informal writing, normalizing text |
| Title Case | Hello World | Article titles, headings, names |
| Sentence case | Hello world | Standard writing, emails, body text |
| camelCase | helloWorld | JavaScript variables, JSON keys |
| PascalCase | HelloWorld | Class names, React components |
| snake_case | hello_world | Python variables, database columns |
| kebab-case | hello-world | CSS classes, HTML attributes, URLs |
| aLtErNaTe | hElLo WoRlD | Memes, social media, emphasis |
This is the question most people get wrong. Title Case capitalizes the first letter of every major word — it is used for article headlines, book titles, and headings. Sentence case only capitalizes the first word and proper nouns — it reads more naturally in body text and subheadings.
American style guides like APA and Chicago favor Title Case for major headings. British and international publications tend to prefer Sentence case. For SEO purposes, either works — consistency matters more than which one you pick.
