What Is a PascalCase Converter?

PascalCase (also called UpperCamelCase) writes identifiers like "HelloWorld" or "UserProfile" — first letter of each word capitalised, no separators. It is the convention for class names in C#, Java, TypeScript and Swift; for type and interface names; and for React, Vue and Angular component names. The visual contrast with camelCase (instances start lowercase) gives readers an immediate hint about what kind of identifier they are looking at.

The converter splits input on whitespace, hyphens, underscores and case boundaries, then capitalises the first letter of each segment and concatenates them. It works equally well on "hello world", "hello-world", "hello_world" or "helloWorld" inputs.

All transforms run in your browser.
