—How to convert text case online
Type or paste your text into the input box. All seven case formats update instantly as you type — no button needed.
Click the 'Copy' button next to any output to copy that specific format to your clipboard.
Title Case skips short function words ('a', 'the', 'of', etc.) that are conventionally left lowercase mid-sentence. camelCase, snake_case, and kebab-case strip punctuation and split on whitespace — useful for converting plain-text names into code-ready identifiers.
Frequently asked questions
- How do I change text to all caps or all lowercase online?
- Paste your text into the input box above. The UPPERCASE and lowercase results appear immediately — click Copy next to whichever you need. No signup or install required.
- How do I convert text to camelCase or snake_case online?
- Paste any plain-text phrase into the input box. The camelCase, snake_case, and kebab-case outputs appear instantly. Spaces and punctuation are removed and word boundaries are marked by capitalisation, underscores, or hyphens respectively.
- Can I change text case without installing any software?
- Yes — this tool runs entirely in your browser. There is nothing to install and it works on Windows, Mac, Linux, and mobile.
- What is the difference between Title Case and Sentence case?
- Title Case capitalizes the first letter of most words (skipping short conjunctions and prepositions mid-sentence), as used in headlines. Sentence case only capitalizes the very first word of each sentence — which reads more naturally as body text or UI labels.
- Why did camelCase remove my spaces and punctuation?
- camelCase, snake_case, and kebab-case are programming identifier formats where spaces aren't allowed. The converter strips punctuation and joins words using the appropriate separator (capitalisation, underscores, or hyphens). If you want to preserve spacing, use Title Case or Sentence case instead.
- Does it work with non-English characters and emoji?
- Yes. The converter works on the full Unicode range — accented characters, non-Latin scripts, and emoji pass through untouched in the case variants that don't transform letter case.
