Paste text, pick a case, copy the result. Everything runs in your browser, so even long documents or confidential drafts stay on your device.

Text case converter features

  • 01

    Eleven cases in one tool

    Switch between natural-language cases (UPPER, lower, Title, Sentence) and developer cases (camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE) instantly. No copy-pasting between different websites.

  • 02

    Smart word detection

    The converter correctly splits CamelCase, snake_case and kebab-case input into words before re-joining them, so you can round-trip between any two cases without losing word boundaries.

    Live character and word counts

    See characters, words and lines of your input update as you type — convenient when writing headlines, social posts or form fields with length limits.

Text case converter FAQ

How do I change text to uppercase?
Paste your text into the input area and choose UPPERCASE from the case list. The output updates instantly and the Copy button puts it on your clipboard.
What is Title Case?
Title Case capitalizes the first letter of each word ("An Example of Title Case"). It's the default style for book titles and headlines in English. Use Sentence case if you only want the first letter of each sentence capitalized.
Can it convert to camelCase or snake_case?
Yes. Pick camelCase, PascalCase, snake_case, kebab-case or CONSTANT_CASE from the secondary case row. The tool splits the input into words (even from existing camel or snake case) and re-joins them in the requested format.
Does it support non-English letters?
Yes. Casing uses the browser's locale-aware toUpperCase and toLowerCase, so accented characters (é → É), German ß, and Cyrillic letters all convert correctly.
Is my text sent to a server?
No. The case converter runs entirely in your browser. Your text is never uploaded, logged or stored.
Is the text case converter free?
Yes. Every Handytool is free with no sign-up, no limits and no watermarks on the output.
