Case Converter
Convert text between lower case, UPPER CASE, Title Case, Sentence case, camelCase, snake_case, kebab-case and PascalCase.
Good to know
- Case changes are deterministic string transforms; acronyms and numbers stay where they are.
Common questions
Does camelCase handle acronyms correctly?
Words are lowercased before joining, so acronyms become normal words. Check identifiers that rely on capitalisation.
Why did accented letters change?
Case mapping is language-independent. Turkish dotted i, for example, may need manual correction.
Can I convert only part of the text?
Yes. Paste only the selection you want to transform.
Is this tool really free?
Yes. There is no account, no paywall and no usage limit. Tools App is funded by aumenso, the studio behind it.
