Convert text between uppercase, lowercase, title case, and sentence case.
Text case matters more than it seems. Headlines, titles, code variable names, and formal documents each follow different capitalization conventions, and manually retyping a paragraph to fix its case is slow and error-prone. A case converter automates the switch between formats instantly, which is especially useful when copying text between contexts that expect different styles — pasting a title into a CMS that wants title case, or cleaning up text that was typed entirely in caps lock by accident.
This is a common step in content editing, technical writing, and even programming, where consistent casing conventions (like camelCase or snake_case in code) matter for readability and standards compliance.
Paste or type your text into the input box, then choose the case format you need: UPPERCASE, lowercase, Title Case, or Sentence case. The converted text appears instantly and can be copied with one click.
Title case capitalizes the first letter of most major words (common in headlines and book titles), while sentence case only capitalizes the first word of each sentence, matching normal prose writing.
Typically, small connector words like "and," "the," "of," and "in" are kept lowercase in proper title case, unless they're the first word of the title, following standard style-guide conventions.
Yes — simply paste your original text again and choose a different case format, or keep the original text somewhere else before converting if you need to preserve it.
Yes, punctuation and numbers are left untouched — only alphabetic characters are affected by the case conversion.
No practical limit — the tool runs in your browser, so it can handle anything from a short headline to several paragraphs of text.
