Free Online Text Case Converter
Change text case when a heading is in the wrong style, a title needs capitals, or code expects camelCase. Convert in your browser and copy the result — no account required.
Available Text Cases
UPPERCASE and lowercase change letter size only. Title Case capitalizes each word and lowercases the rest. Sentence case capitalizes the start of sentences. Capitalized Case capitalizes the first letter of each word and leaves the rest as you typed it. Alternating and toggle cases flip letter size. camelCase, PascalCase, snake_case, and kebab-case join words for names and URLs.

Frequently Asked Questions
What cases can I convert between?
UPPERCASE, lowercase, Title Case, Sentence case, Capitalized Case, alternating case, toggle case, camelCase, PascalCase, snake_case, and kebab-case.
Does conversion rewrite my wording?
No. It only changes capitalization and, for camelCase, snake_case, and kebab-case, how words are joined. It is not an AI writing tool.
Will my line breaks be removed?
Simple case changes keep spaces and new lines. Identifier styles such as camelCase treat spaces and punctuation as word separators, which is the usual result for those formats.
Is the case converter free?
Yes. Convert and copy text without an account.
Is my text uploaded?
No. Your text is processed in your browser and is not uploaded.
