Which case styles are supported?
Uppercase, lowercase, title case, camelCase, PascalCase, kebab-case, snake_case, and CONSTANT_CASE are supported.
Will punctuation be preserved?
For word-based cases, punctuation is treated as a separator. Uppercase and lowercase preserve punctuation.
Can I make URL slugs with it?
Use kebab-case for simple slugs such as user-profile-image. For URL escaping, use the URL Encode Decode Tool after that.
What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase word. PascalCase capitalizes the first word too.
Is my data uploaded to a server?
No. The tool runs in your browser, so the text you paste stays on your device.
