Frequently asked questions

Is the case converter free?
Yes. It's completely free, needs no sign-up, and runs entirely in your browser.
What's the difference between camelCase, snake_case, and kebab-case?
camelCase joins words with no spaces and capitalizes each word after the first (myVariableName); snake_case joins lowercase words with underscores (my_variable_name); kebab-case joins lowercase words with hyphens (my-variable-name). The converter splits your text into words first, so it handles input in any of these styles.
Is my text uploaded anywhere?
No. All conversion happens locally in your browser — your text never leaves your device.
