Case Converter rewrites your text in the case you need: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case, or kebab-case. Paste any text, pick a style, and copy the result. It is handy for headings, code identifiers, slugs, and cleaning up text pasted from other apps. Everything is transformed in your browser and your text is never uploaded to any server.
Common questions
What case styles are supported?
UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case, and kebab-case. Pick any style and the result updates immediately.
How does Title Case decide what to capitalize?
Title Case capitalizes the first letter of every word. It is a simple, predictable rule and does not lowercase short words like “of” or “the”, so you keep full control.
What is the difference between camelCase, snake_case, and kebab-case?
All three join words without spaces. camelCase capitalizes each word after the first (myVariableName), snake_case joins with underscores (my_variable_name), and kebab-case joins with hyphens (my-variable-name).
Can I copy the result?
Yes. Click Copy to place the converted text on your clipboard. If your browser blocks clipboard access you can still select the output and copy it manually.
Is my text uploaded anywhere?
No. All conversion happens in your browser tab. Your text never leaves your device and nothing is stored.
