Case Converter

If you've ever pasted a block of text and realized it's all in the wrong case, you know how tedious it is to fix manually. Our free case converter tool lets you transform any text into the exact format you need — in under a second, no downloads, no sign-up.

Whether you're a developer naming variables, a writer formatting headings, or someone who accidentally typed an entire sentence in caps lock, this tool has you covered. It supports twelve different case formats, from the everyday to the developer-specific.

Upper and Lower case are exactly what you'd expect — full caps or all lowercase. These come in handy when copy-pasting content from PDFs or old documents that didn't respect formatting.

Title Case capitalizes the first letter of every word, which is the standard format for article headings, product names, and book titles. Sentence case is a bit smarter — it only capitalizes the first word after a period, making it perfect for paragraphs and UI copy.

camelCase and PascalCase are used constantly in programming. JavaScript developers tend to use camelCase for variables (like myVariableName), while PascalCase is standard for class names and React components (MyComponent).

snake_case is the go-to for Python and database column names. kebab-case shows up everywhere in URLs, CSS class names, and HTML attributes. CONSTANT_CASE is how most languages define environment variables and constants.

dot.case is less common but used in configuration files and some logging systems. And if you need something a bit more playful, aLtErNaTiNg and iNVERSE case are always there for memes and sarcastic internet discourse.

The tool works entirely in your browser — nothing is sent to a server. Paste your text, click your target case, and copy the result. That's it.
