Case converter
Turn text into UPPERCASE, lowercase, Title Case, camelCase and more.
Paste any text and convert it in one click between eight formats: UPPERCASE, lowercase, Sentence case, Title Case, iNVERTED and the programming formats camelCase, snake_case and kebab-case. Perfect for fixing that paragraph typed with Caps Lock on or standardizing variable names — without retyping anything and without sending your text to any server.
Frequently asked questions
Does the converter handle accented characters?
Yes. Conversion follows locale rules, so "ação" becomes "AÇÃO" and "ÓTIMO" becomes "ótimo" correctly — including ç, ã, é and other accented characters.
How does "Sentence case" work?
It lowercases everything, then capitalizes the first letter of the text, of each line and of each sentence after a period, exclamation or question mark — the format of an ordinary paragraph.
What are camelCase, snake_case and kebab-case for?
They are naming conventions used in programming: camelCase in JavaScript and Java, snake_case in Python and databases, kebab-case in URLs and CSS file names. The converter splits words automatically and assembles the chosen format.
