Frequently asked questions
What case formats can I convert to?
You can convert text to UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case, kebab-case, and a URL slug. Each option rewrites the text in the box instantly so you can chain conversions if needed.
Is my text uploaded or kept private?
Your text is never uploaded. The converter runs 100% in your browser, so everything is processed locally on your device and nothing is sent to a server — making it safe for sensitive or confidential content.
Is there a limit on how much text I can convert?
There is no fixed character or word limit. Since the conversion happens locally in your browser, you can paste short snippets or large blocks of text, limited only by your device's memory.
What is 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).
How does the URL slug option work?
The slug option lowercases your text, strips accents and diacritics, and joins words with hyphens to produce a clean, URL-friendly string like my-page-title — ideal for blog post and page URLs.
Do I need to install anything or create an account?
No. The case converter is a free web tool that works directly in your browser with no sign-up, downloads, or installation. Just open the page, paste your text, and convert.
