Text Case Converter Online — UPPER, lower, Title, camel & More

How to convert text case (3 steps)

1. Paste your text. A heading, a variable name, a list of slugs — anything.
2. Pick the case. UPPERCASE for banners and code constants, Title Case for article headings, camelCase/PascalCase for code identifiers, snake_case for Python and database columns, kebab-case for URLs and file names, aLtErNaTiNg for memes.
3. Copy the result. One click copies it to your clipboard. Multi-line text keeps its line breaks — every line is converted independently.

Why case tools live in every dev's toolbar

Case switching is one of those micro-tasks that happens dozens of times a day: renaming variables to match a language's convention, turning a title into a URL slug, or formatting a CSV of names. Browser-based means no round trip — and no copy-paste of client names or code into a stranger's input box, which is quietly a data leak when the text is sensitive.

FAQ

• Does it handle multiple lines? Yes — each line is converted independently, which makes it great for bulk-renaming lists.
• How does Title Case handle "of" and "the"? It capitalizes every word except common short words (a, an, the, and, or, of, to, in, on, for, at, by) unless they start the text — the standard headline style.
• Is my text uploaded? No — conversion is pure string math in your browser.
