About the case styles
- UPPERCASE — every letter capital, great for headings and emphasis.
- lowercase — every letter small, tidy for tags and casual text.
- Title Case — the first letter of each word capitalised, like a book title.
- Sentence case — only the first letter of each sentence capitalised.
- camelCase — words joined with no spaces, each new word capitalised — common in code.
- snake_case — lowercase words joined by underscores, popular in Python and databases.
- kebab-case — lowercase words joined by hyphens, handy for URLs and CSS class names.
- CONSTANT_CASE — uppercase words joined by underscores, used for constants and config keys.

Frequently Asked Questions
Which case styles can I convert to? ▼
Eight of them: UPPERCASE, lowercase, Title Case, Sentence case,
camelCase, snake_case, kebab-case and CONSTANT_CASE. Tap any one to preview it live.What's the difference between camelCase and snake_case? ▼
camelCase joins words with no spaces and capitalises each new word (like myVariableName), while snake_case uses all-lowercase words joined by underscores (like my_variable_name). Both are common in code.Does it work on programming variable names? ▼
Yes. The tool splits on spaces, underscores, hyphens and even camelCase humps, so an existing name like
myVariableName converts cleanly into any other style.Will it change my numbers or punctuation? ▼
Numbers stay as they are. For the joined styles like snake_case and kebab-case, punctuation is treated as a word separator; UPPERCASE, lowercase, Title and Sentence case leave your punctuation in place.
Is there a limit on how much text I can convert? ▼
No. You can paste a single word or many paragraphs — everything converts instantly as you type.
Is my text uploaded anywhere? ▼
No. Everything happens right here in your browser on your own device. Your text is never uploaded and we never see it.
