Convert text between uppercase, lowercase, title case, sentence case, camelCase, snake_case, kebab-case, toggle case — plus reverse, flip words, and reverse each word.
Paste any text into the input box and pick a conversion mode: UPPERCASE, lowercase, Title Case or Sentence case. The result appears instantly and you can copy it with one click — no need to retype or format manually.
Use it to normalize imported data, fix ALL-CAPS paragraphs in emails, or clean up article headings before publishing. Title Case capitalizes most words but leaves small conjunctions lowercase; Sentence case only capitalizes the first word, which suits formal writing and product descriptions.
For code or database keys, stick to lowercase consistently; for file names on shared drives, use Title Case sparingly to avoid duplicate-file confusion. The tool preserves all non-letter characters, so URLs and emails remain intact while casing changes.
Copy a paragraph, run it through each mode once, and you will see how casing changes reading rhythm. Editors and publishers use this to normalize headlines: Sentence case for news, Title Case for magazine covers, and lowercase for modern tech branding.
This free case converter transforms text between 8+ letter cases and 3 reversal modes. Whether you need uppercase for headings, lowercase for URLs, title case for article titles, camelCase for programming, or text reversal for creative projects — it's all in one tool. Every conversion happens in your browser — nothing is sent to any server.
Title Case capitalizes the first letter of every word (Hello World). Sentence case capitalizes only the first letter of each sentence (Hello world. How are you?).
camelCase (helloWorld) is standard in JavaScript, Java, and C#. snake_case (hello_world) is preferred in Python, Ruby, and database column names.
