About case conversion
Four direct text modes
The converter applies one selected mode to the whole pasted text. UPPERCASE and lowercase use the browser string casing rules, Title Case capitalizes each word with a simple word pattern, and random case changes only Latin letters while leaving numbers and punctuation unchanged.
Not an identifier formatter
Use this page for quick copy cleanup, heading checks, labels, or throwaway test text. It does not split words by separators, infer programming naming conventions, or generate camel case and snake case variants, so code identifiers still need manual review.
FAQ
Common questions and answers about this topic.
What case styles are supported?
UPPERCASE, lowercase, Title Case, and RaNdOm CaSe are supported. You can quickly switch between styles to format variable names, titles, or any text.
When should I use different case styles?
UPPERCASE is useful for shouting labels or constants, lowercase for normalizing pasted text, Title Case for headings, and random case for visual testing or examples. This page does not create camelCase or snake_case identifiers.
Is my data sent to any server?
No, case conversion is performed entirely in your browser. Your text is transformed locally with JavaScript and never sent to any server.
