Case Converter: 9 Formats, One Click
UPPERCASE, lowercase, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE — pick a button, copy the result
Paste text once and switch it between nine capitalization formats with a single click. Alongside UPPERCASE, lowercase, Title Case, and sentence case, it covers the identifier styles developers actually need — camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE — and it splits existing camelCase input back into words automatically, so you can convert myVariableName to MY_VARIABLE_NAME in one step. No options to configure and nothing to submit: everything runs in your browser. If you're capitalizing prose or headlines and want style-guide rules for words like 'of' and 'the', use the Sentence Case & Title Case Converter instead.
🔒 Everything runs 100% in your browser. Your files and input are never uploaded to any server.
How to use

FAQ
- What are camelCase and snake_case?
- camelCase joins words with a capital letter on each new word, like 'myVariableName', while snake_case joins them with underscores, like 'my_variable_name'. Both are common naming styles for variables and file names.
- Does it work with non-Latin text?
- Casing only applies to the Latin alphabet. Characters in other scripts are left unchanged, and only the letters and numbers are converted.
- Can it handle long documents?
- Yes. Everything is processed instantly in your browser, so it converts text of any length in a flash.
